ocfs2: ip_alloc_sem should be taken in ocfs2_get_block()
ip_alloc_sem should be taken in ocfs2_get_block() when reading file in
DIRECT mode to prevent concurrent access to extent tree with
ocfs2_dio_end_io_write(), which may cause BUGON in the following
situation:
read file 'A' end_io of writing file 'A'
vfs_read

ocfs2: fix cluster hang after a node dies
When a node dies, other live nodes have to choose a new master for an
existed lock resource mastered by the dead node.
As for ocfs2/dlm implementation, this is done by function -
dlm_move_lockres_to_recovery_list which marks those lock rsources as
DLM_LOCK_RES_RECOVERING and manages them via a list from which DLM
changes lock resource's master later.
So without invoking dlm_move_lockres_to_recovery_list, no master will be
choosed after dlm recovery accomplishment since no lock resource can be
found through ::resource list.
What's worse is that if DLM_LOCK_RES_RECOVERING is not marked for lock
resources mastered a dead node, it will break up synchronization among
nodes.
So invoke dlm_move_lockres_to_recovery_list again.

m32r: fix endianness constraints
The m32r Kconfig provides both CPU_BIG_ENDIAN and CPU_LITTLE_ENDIAN
configuration options. As they are user-selectable and independent,
this allows invalid configurations:
- All m32r defconfigs build a big endian kernel, but CPU_BIG_ENDIAN is
not set, causing compiler warnings like:
include/linux/byteorder/big_endian.h:7:2: warning: #warning inconsistent configuration, needs CONFIG_CPU_BIG_ENDIAN [-Wcpp]
#warning inconsistent configuration, needs CONFIG_CPU_BIG_ENDIAN
^
- Since commit

Pull arm64 updates from Will Deacon:
"The big highlight is support for the Scalable Vector Extension (SVE)
which required extensive ABI work to ensure we don't break existing
applications by blowing away their signal stack with the rather large
new vector context (<= 2 kbit per vector register). There's further
work to be done optimising things like exception return, but the ABI
is solid now.
Much of the line count comes from some new PMU drivers we have, but
they're pretty self-contained and I suspect we'll have more of them in
future.

RISC-V Port for Linux 4.15 v9
This tag contains the core RISC-V Linux port, which has been through
nine rounds of review on various mailing lists. The port is not
complete: there's some cleanup patches moving through the review
process, a whole bunch of drivers that need some work, and a lot of
feature additions that will be needed.
The patches contained in this tag have been through nine rounds of
review on the various mailing lists. I have some outstanding cleanup
patches, but since there's been so much review on these patches I
thought it would be best to submit them as-is and then submit explicit
cleanup patches so everyone can review them. This first patch set is
big enough that it's a bit of a pain to constantly rewrite, and it's
caused a few headaches with various contributors.
The port is definately a work in progress. While what's there builds
and boots with 4.14, it's a bit hard to actually see anything happen
because there are no device drivers yet. I maintain a staging branch
that contains all the device drivers and cleanup that actually works,
but those patches won't all be ready for a while. I'd like to get what
we currently have into your tree so everyone can start working from a
single base -- of particular importance is allowing the glibc
upstreaming process to proceed so we can sort out any possibly lingering
user-visible ABI problems we might have.
Copied below is the ChangeLog that contains the history of this patch
set:
(v9) As per suggestions on our v8 patch set, I've split the core architecture code
out from our drivers and would like to submit this patch set to be included
into linux-next, with the goal being to be merged in during the next merge
window. This patch set is based on 4.14-rc2, but if it's better to have it
based on something else then I can change it around.
This patch set contains just the core arch code for RISC-V, so while it builds
an nominally boots, you can't print or take an interrupt so it's not that
useful. If you're looking to actually boot a system it would probably be
better to use the full patch set listed below.
We've collected a handful of tags from reviewers, and the remainder of the
patch set only got minimal feedback last time. Here's what changed:
* We now use the device tree to initialize the timer driver so it's less
tighly coupled with the arch port.
* I cleaned up the defconfigs -- there's actually now just one, and it's
empty. For now I think we're OK with what the kernel sets as defaults, but
I anticipate we'll begin to expand this as people start to use the port
more.
* The VDSO symbols version is sane.
* We WFI while spinning in the boot loop.
* A handful of comments have been added.
While there are still a handful of FIXMEs in this patch set, we've started to
get enough interest from various users and contributors that maintaining an out
of tree patch set is starting to become a big burden. Hopefully the patches
are good enough to merge now, which will at least get everyone working in a
more reasonable manner as we clean up the remaining issues.
This patch set is also availiable on github
https://github.com/riscv/riscv-linux/tree/riscv-for-submission-v9-arch
as is the entire patch set necessary to get a more functional RISC-V system up
and running, including a handful of patches that aren't ready for upstream yet.
https://github.com/riscv/riscv-linux/tree/riscv-for-submission-v9
Hopefully I've managed to get everyone's feedback
Here's the change highlights from the whole patch set:
(v8) I know it may not be the ideal time to submit a patch set right now, as
it's the middle of the merge window, but things have calmed down quite a bit in
the last month so I thought it would be good to get everyone on the same page.
There's been a handful of changes since the last patch set, but most of them
are fairly minor:
* We changed PAGE_OFFSET to allowing mapping more physical memory on 64-bit
systems. This is user configurable, as it triggers a different code model
that generates slightly less efficient code.
* The device tree binding documentation is back, I'd managed to lose it at some
point.
* We now pass the atomic64 test suite. The SBI timer driver has been
* refactored.
(v7) It's been a while since my last patch set, but the changes han been fairly
minimal:
* The PCI cleanup patches have been dropped, we'll do them as a separate patch
set later.
* We've the Kconfig entries from CONFIG_ISA_* to CONFIG_RISCV_ISA_*, to make
grep easier.
* There have been a handful of memory model related tweaks in I/O land,
particularly relating the PCI and the upcoming platform specification.
There are significant comments in the relevant files. This is still a WIP,
but I think we're close to getting as good as we're going to get until we
end up with some more specifications.
(v6) As it's been only a day since the v5 patch set, the changes are pretty
minimal:
* The patch set is now based on linux-next/master, which I believe is a better
base now that we're getting closer to upstream.
* EARLY_PRINTK is no longer an option. Since the SBI console is reasonable,
there's no penalty to enabling it (and thus no benefit to disabling it).
* The mmap syscalls were refactored a bit.
(v5) Things have really started to calm down, so this is fairly similar to the
v4 patch set. The most interesting changes include:
* We've moved back to a single patch set.
* SMP support has been fixed, I was accidentally running on a non-SMP
configuration. There were various mistakes all over the tree as a result of
this.
* The cmpxchg syscalls have been removed, as they were deemed a bad idea. As
a result, RISC-V Linux systems mandate the A extension. The corresponding
Kconfig entry to enable builds on non-A systems has been removed.
* A few more atomic fixes: mostly fence changes, but those resulted in a
handful of additional macros that were no longer necessary.
* riscv_early_sie has been removed.
(v4) There have only been a few changes since the v3 patch set:
* The cmpxchg64 syscall is no longer enabled on 32-bit systems. It's not
possible to provide this on SMP systems, and it's not necessary as glibc
knows not to call it.
* We provide a ELF_HWCAP so users can determine the ISA of the machine the
kernel is running on.
* The multi-line comments are in a better form.
* There were a handful of headers that could be replaced with the asm-generic
versions, and a few unnecessary definitions.
* We no longer use printk, but instead use pr_*.
* A few Kconfig and defconfig entries have been cleaned up.
(v3) A highlight of the changes since the v2 patch set includes:
* We've split out all our drivers into separate patch sets, which I've already
sent out to the relevant maintainers. I haven't included those patches in
this patch set, but some of them are necessary to build our port. A git
tree that contains all our patch sets merged together lives at
<https://github.com/riscv/riscv-linux/tree/riscv-for-submission-v3>.
* The patch set is now split up differently: rather than being split per
directory it is split per topic. Hopefully this will make it easier to
review the port on the mailing list. The split is a bit rough, so you
probably still want to look at the patch set as a whole.
* atomic.h has been completely rewritten and is hopefully now correct. I've
attempted to sanitize the various other memory model related code as well,
and I think it should all be sane now aside from a handful of FIXMEs
commented in the code.
* We've changed the cmpexchg syscall to always exist and to not be
multiplexed. There is also a VDSO entry for compare and exchange, which
allows kernels with the A extension to execute user code without the A
extension reasonably fast.
* Our user-visible register state now contains enough space for the Q
extension for 128-bit floating point, as well as a few words to allow
extensibility to future ISA extensions like the eventual V extension for
vectors.
* A handful of driver cleanups, but these have been split into separate patch
sets now so I won't duplicate them here.
(v2) A highlight of the changes since the v1 patch set includes:
* We've split out our drivers into the right places, which means now there's
a lot more patches. I'll be submitting these patches to various subsystem
maintainers and including them in any future RISC-V patch sets until
they've been merged.
* The SBI console driver has been completely rewritten to use the HVC helpers
and is now significantly smaller.
* We've begun to use weaker barriers as opposed to just the big "fence".
There's still some work to do here, specifically:
- We need fences in the relaxed MMIO functions.
- The non-relaxed MMIO functions are missing R/W bits on their fences.
- Many AMOs need the aq and rl bits set.
* We now have thread_info in task_struct. As a result, sscratch now contains
TP instead of SP. This was necessary because thread_info is no longer on
the stack.
* A few shared routines have been added that we use instead of creating
another arch copy.

- We now pass the atomic64 test suite
- The SBI timer driver has been refactored.
(v7) It's been a while since my last patch set, but the changes han
been fairly minimal:
- The PCI cleanup patches have been dropped, we'll do them as a
separate patch set later.
- We've the Kconfig entries from CONFIG_ISA_* to
CONFIG_RISCV_ISA_*, to make grep easier.
- There have been a handful of memory model related tweaks in
I/O land, particularly relating the PCI and the upcoming
platform specification. There are significant comments in the
relevant files. This is still a WIP, but I think we're close
to getting as good as we're going to get until we end up with
some more specifications.
(v6) As it's been only a day since the v5 patch set, the changes are
pretty minimal:
- The patch set is now based on linux-next/master, which I
believe is a better base now that we're getting closer to
upstream.
- EARLY_PRINTK is no longer an option. Since the SBI console is
reasonable, there's no penalty to enabling it (and thus no
benefit to disabling it).
- The mmap syscalls were refactored a bit.
(v5) Things have really started to calm down, so this is fairly
similar to the v4 patch set. The most interesting changes
include:
- We've moved back to a single patch set.
- SMP support has been fixed, I was accidentally running on a
non-SMP configuration. There were various mistakes all over
the tree as a result of this.
- The cmpxchg syscalls have been removed, as they were deemed a
bad idea. As a result, RISC-V Linux systems mandate the A
extension. The corresponding Kconfig entry to enable builds
on non-A systems has been removed.
- A few more atomic fixes: mostly fence changes, but those
resulted in a handful of additional macros that were no
longer necessary.
- riscv_early_sie has been removed.
(v4) There have only been a few changes since the v3 patch set:
- The cmpxchg64 syscall is no longer enabled on 32-bit systems.
It's not possible to provide this on SMP systems, and it's
not necessary as glibc knows not to call it.
- We provide a ELF_HWCAP so users can determine the ISA of the
machine the kernel is running on.
- The multi-line comments are in a better form.
- There were a handful of headers that could be replaced with
the asm-generic versions, and a few unnecessary definitions.
- We no longer use printk, but instead use pr_*.
- A few Kconfig and defconfig entries have been cleaned up.
(v3) A highlight of the changes since the v2 patch set includes:
- We've split out all our drivers into separate patch sets,
which I've already sent out to the relevant maintainers. I
haven't included those patches in this patch set, but some of
them are necessary to build our port.
- The patch set is now split up differently: rather than being
split per directory it is split per topic. Hopefully this
will make it easier to review the port on the mailing list.
The split is a bit rough, so you probably still want to look
at the patch set as a whole.
- atomic.h has been completely rewritten and is hopefully now
correct. I've attempted to sanitize the various other memory
model related code as well, and I think it should all be sane
now aside from a handful of FIXMEs commented in the code.
- We've changed the cmpexchg syscall to always exist and to not
be multiplexed. There is also a VDSO entry for compare and
exchange, which allows kernels with the A extension to
execute user code without the A extension reasonably fast.
- Our user-visible register state now contains enough space for
the Q extension for 128-bit floating point, as well as a few
words to allow extensibility to future ISA extensions like
the eventual V extension for vectors.
- A handful of driver cleanups, but these have been split into
separate patch sets now so I won't duplicate them here.
(v2) A highlight of the changes since the v1 patch set includes:
- We've split out our drivers into the right places, which
means now there's a lot more patches. I'll be submitting
these patches to various subsystem maintainers and including
them in any future RISC-V patch sets until they've been
merged.
- The SBI console driver has been completely rewritten to use
the HVC helpers and is now significantly smaller.
- We've begun to use weaker barriers as opposed to just the big
"fence". There's still some work to do here, specifically:
- We need fences in the relaxed MMIO functions.
- The non-relaxed MMIO functions are missing R/W bits on their fences.
- Many AMOs need the aq and rl bits set.
- We now have thread_info in task_struct. As a result, sscratch
now contains TP instead of SP. This was necessary because
thread_info is no longer on the stack.
- A few shared routines have been added that we use instead of
creating another arch copy"

sound updates for 4.15-rc1
There are no big surprising changes in this cycle, yet not too
boring, either. The biggest change from diffstat POV is the removal
of the legacy OSS driver codes that have been already disabled for a
long time. This will bring a few trivial merge conflicts.
As new features in ASoC side, there are two things: a new AC97 bus
implementation and AMD Stony platform support. Both include the
relevant changes shared with other subsystems, e.g. AC97 MFD changes
and DRM AMD changes.
Some other highlighted topics are:
- A bunch of USB-audio drivers got the hardening against the malicious
device accesses with a new helper code for endpoint sanity check.
- Lots of cleanups for ASoC Intel platform code, including support for
their open source audio firmware.
- Continued ASoC core componentization works.
- Support for scaling MCLK with sample rate in ASoC simple-card.
- Stabler PCM hot-unplug capability, especially for ASoC usages.

Merge branch 'i2c/for-4.15' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
"This contains two bigger than usual tree-wide changes this time. They
all have proper acks, caused no merge conflicts in linux-next where
they have been for a while. They are namely:
- to-gpiod conversion of the i2c-gpio driver and its users (touching
arch/* and drivers/mfd/*)
- adding a sbs-manager based on I2C core updates to SMBus alerts
(touching drivers/power/*)
Other notable changes:
- i2c_boardinfo can now carry a dev_name to be used when the device
is created. This is because some devices in ACPI world need fixed
names to find the regulators.
- the designware driver got a long discussed overhaul of its PM
handling. img-scb and davinci got PM support, too.
- at24 driver has way better OF support. And it has a new maintainer.
Thanks Bartosz for stepping up!
The rest is regular driver updates and fixes"

This is the bulk of GPIO changes for the v4.15 kernel cycle:
CORE:
- Fix the semantics of raw GPIO to actually be raw. No
inversion semantics as before, but also no open draining,
and allow the raw operations to affect lines used for
interrupts as the caller supposedly knows what they are
doing if they are getting the big hammer.
- Rewrote the __inner_function() notation calls to names that
make more sense. I just find this kind of code disturbing.
- Drop the .irq_base() field from the gpiochip since now all
IRQs are mapped dynamically. This is nice.
- Support for .get_multiple() in the core driver API. This
allows us to read several GPIO lines with a single
register read. This has high value for some usecases: it
can be used to create oscilloscopes and signal analyzers
and other things that rely on reading several lines at
exactly the same instant. Also a generally nice
optimization. This uses the new assign_bit() macro from
the bitops lib that was ACKed by Andrew Morton and
is implemented for two drivers, one of them being the
generic MMIO driver so everyone using that will be able
to benefit from this.
- Do not allow requests of Open Drain and Open Source
setting of a GPIO line simultaneously. If the hardware
actually supports enabling both at the same time the
electrical result would be disastrous.
- A new interrupt chip core helper. This will be helpful
to deal with "banked" GPIOs, which means GPIO controllers
with several logical blocks of GPIO inside them. This
is several gpiochips per device in the device model, in
contrast to the case when there is a 1-to-1 relationship
between a device and a gpiochip.
NEW DRIVERS:
- Maxim MAX3191x industrial serializer, a very interesting
piece of professional I/O hardware.
- Uniphier GPIO driver. This is the GPIO block from the
recent Socionext (ex Fujitsu and Panasonic) platform.
- Tegra 186 driver. This is based on the new banked GPIO
infrastructure.
OTHER IMPROVEMENTS:
- Some documentation improvements.
- Wakeup support for the DesignWare DWAPB GPIO controller.
- Reset line support on the DesignWare DWAPB GPIO controller.
- Several non-critical bug fixes and improvements for the
Broadcom BRCMSTB driver.
- Misc non-critical bug fixes like exotic errorpaths, removal
of dead code etc.
- Explicit comments on fall-through switch() statements.

SCSI misc on 20171114
This is mostly updates of the usual suspects: lpfc, qla2xxx, hisi_sas, megaraid_sas, pm80xx, mpt3sas, be2iscsi, hpsa. and a host of minor updates.

Merge branch 'for-4.15/block' of git://git.kernel.dk/linux-block
Pull core block layer updates from Jens Axboe:
"This is the main pull request for block storage for 4.15-rc1.
Nothing out of the ordinary in here, and no API changes or anything
like that. Just various new features for drivers, core changes, etc.
In particular, this pull request contains:
- A patch series from Bart, closing the whole on blk/scsi-mq queue
quescing.
- A series from Christoph, building towards hidden gendisks (for
multipath) and ability to move bio chains around.
- NVMe
- Support for native multipath for NVMe (Christoph).
- Userspace notifications for AENs (Keith).
- Command side-effects support (Keith).
- SGL support (Chaitanya Kulkarni)
- FC fixes and improvements (James Smart)
- Lots of fixes and tweaks (Various)
- bcache
- New maintainer (Michael Lyle)
- Writeback control improvements (Michael)
- Various fixes (Coly, Elena, Eric, Liang, et al)
- lightnvm updates, mostly centered around the pblk interface
(Javier, Hans, and Rakesh).
- Removal of unused bio/bvec kmap atomic interfaces (me, Christoph)
- Writeback series that fix the much discussed hundreds of millions
of sync-all units. This goes all the way, as discussed previously
(me).
- Fix for missing wakeup on writeback timer adjustments (Yafang
Shao).
- Fix laptop mode on blk-mq (me).
- {mq,name} tupple lookup for IO schedulers, allowing us to have
alias names. This means you can use 'deadline' on both !mq and on
mq (where it's called mq-deadline). (me).
- blktrace race fix, oopsing on sg load (me).
- blk-mq optimizations (me).
- Obscure waitqueue race fix for kyber (Omar).
- NBD fixes (Josef).
- Disable writeback throttling by default on bfq, like we do on cfq
(Luca Miccio).
- Series from Ming that enable us to treat flush requests on blk-mq
like any other request. This is a really nice cleanup.
- Series from Ming that improves merging on blk-mq with schedulers,
getting us closer to flipping the switch on scsi-mq again.
- BFQ updates (Paolo).
- blk-mq atomic flags memory ordering fixes (Peter Z).
- Loop cgroup support (Shaohua).
- Lots of minor fixes from lots of different folks, both for core and
driver code"

We've got a total of 17 GFS2 patches for this merge window. The
patches are basically in three categories: (1) patches related to
broken xfstest cases, (2) patches related to improving iomap and
start using it in GFS2, and (3) general typos and clarifications.
Please note that one of the iomap patches extends beyond GFS2 and
affects other file systems, but it was publically reviewed by a
variety of file system people in the community.
1. Andreas has a patch that simply renames variable 'bsize' to 'factor'
to clarify the logic related to gfs2_block_map.
2. He also has a patch to correctly set ctime in the setflags ioctl,
which fixes broken xfstests test 277.
3. He also fixed broken xfstest 258, due to an atime initialization
problem.
4. He also fixed broken xfstest 307, in which GFS2 was not setting
ctime when setting acls.
5. He has a patch to switch general iomap code from blkno to disk
offset for a variety of file systems.
6. He has a patch to add a new IOMAP_F_DATA_INLINE flag for iomap
to indicate blocks that have data mixed with metadata.
7. I contributed a patch to make inode height info part of the
'metapath' data structure to facilitate using iomap in GFS2.
8. I have a patch to start using iomap inside GFS2 and switch GFS2's
block_map functions to use iomap under the covers.
9. I have a patch to switch GFS2's fiemap implementation from using
block_map to using iomap under the covers.
10. Andreas has a patch to implement SEEK_HOLE and SEEK_DATA via
iomap in GFS2.
11. I have a patch related to journaled data pages not being properly
synced to media when writing inodes. This was caught with xfstests.
12. I have a patch to fix another failing xfstest case in which
switching a file from ordered_write to journaled data via set_flags
caused a deadlock.
13. Andreas has a patch to fix failing xfstest case 066, which was
due to not properly syncing dirty inodes when changing extended
attributes.
14. Andreas fixed a minor typo in a comment.
15. Andreas contributed a patch to partially fix xfstest 424, which
involved GET_FLAGS and SET_FLAGS ioctl. This is also a cleanup
and simplification of the translation of flags from fs flags to
gfs2 flags.
16. He also added support for STATX_ATTR_ in statx, which fixed broken
xfstest 424.
17. He also contributed a fix for failing xfstest 093 which fixes a
recursive glock problem with gfs2_xattr_get and _set.

Merge branch 'for-4.15' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs updates from David Sterba:
"There are some new user features and the usual load of invisible
enhancements or cleanups.
New features:
- extend mount options to specify zlib compression level, -o
compress=zlib:9
- v2 of ioctl "extent to inode mapping", addressing a usecase where
we want to retrieve more but inaccurate results and do the
postprocessing in userspace, aiding defragmentation or
deduplication tools
- populate compression heuristics logic, do data sampling and try to
guess compressibility by: looking for repeated patterns, counting
unique byte values and distribution, calculating Shannon entropy;
this will need more benchmarking and possibly fine tuning, but the
base should be good enough
- enable indexing for btrfs as lower filesystem in overlayfs
- speedup page cache readahead during send on large files
Internal enhancements:
- more sanity checks of b-tree items when reading them from disk
- more EINVAL/EUCLEAN fixups, missing BLK_STS_* conversion, other
errno or error handling fixes
- remove some homegrown IO-related logic, that's been obsoleted by
core block layer changes (batching, plug/unplug, own counters)
- add ref-verify, optional debugging feature to verify extent
reference accounting
- simplify code handling outstanding extents, make it more clear
where and how the accounting is done
- make delalloc reservations per-inode, simplify the code and make
the logic more straightforward
- extensive cleanup of delayed refs code
Notable fixes:
- fix send ioctl on 32bit with 64bit kernel"

New in this version:
- Refactor the incore extent map manipulations to use a cursor instead of
directly modifying extent data.
- Refactor the incore extent map cursor to use an in-memory btree instead
of a single high-order allocation. This eliminates a major source of
complaints about insufficient memory when opening a heavily fragmented
file into a system whose memory is also heavily fragmented.
- Fix a longstanding bug where deleting a file with a complex extended
attribute btree incorrectly handled memory pointers, which could lead
to memory corruption.
- Improve metadata validation to eliminate crashing problems found while
fuzzing xfs.
- Move the error injection tag definitions into libxfs to be shared with
userspace components.
- Fix some log recovery bugs where we'd underflow log block position
vector and incorrectly fail log recovery.
- Drain the buffer lru after log recovery to force recovered buffers back
through the verifiers after mount. On a v4 filesystem the log never
attaches verifiers during log replay (v5 does), so we could end up with
buffers marked verified but without having ever been verified.
- Fix various other bugs.
- Introduce the first part of a new online fsck tool. The new fsck tool
will be able to iterate every piece of metadata in the filesystem to
look for obvious errors and corruptions. In the next release cycle
the checking will be extended to cross-reference with the other fs
metadata, so this feature should only be used by the developers in the
mean time.

Merge tag 'xfs-4.15-merge-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Darrick Wong:
"xfs: great scads of new stuff for 4.15.
This merge cycle, we're making some substantive changes to XFS. The
in-core extent mappings have been refactored to use proper iterators
and a btree to handle heavily fragmented files without needing
high-order memory allocations; some important log recovery bug fixes;
and the first part of the online fsck functionality.
(The online fsck feature is disabled by default and more pieces of it
will be coming in future release cycles.)
This giant pile of patches has been run through a full xfstests run
over the weekend and through a quick xfstests run against this
morning's master, with no major failures reported.
New in this version:
- Refactor the incore extent map manipulations to use a cursor
instead of directly modifying extent data.
- Refactor the incore extent map cursor to use an in-memory btree
instead of a single high-order allocation. This eliminates a major
