SCSI misc on 20180131
This is mostly updates of the usual driver suspects: arcmsr, scsi_debug, mpt3sas, lpfc, cxlflash, qla2xxx, aacraid, megaraid_sas, hisi_sas. We also have a rework of the libsas hotplug handling to make it more robust, a slew of 32 bit time conversions and fixes, and a host of the usual minor updates and style changes. The biggest potential for regressions is the libsas hotplug changes, but so far they seem stable under testing. Signed-off-by: James E.J.

- DM core fixes to ensure that bio submission follows a depth-first tree
walk; this is critical to allow forward progress without the need to use the bioset's BIOSET_NEED_RESCUER. - Remove DM core's BIOSET_NEED_RESCUER based dm_offload infrastructure. - DM core cleanups and improvements to make bio-based DM more efficient (e.g. reduced memory footprint as well leveraging per-bio-data more). - Introduce new bio-based mode (DM_TYPE_NVME_BIO_BASED) that leverages the more direct IO submission path in the block layer; this mode is used by DM multipath and also optimizes targets like DM thin-pool that stack directly on NVMe data device. - DM multipath improvements to factor out legacy SCSI-only (e.g. scsi_dh) code paths to allow for more optimized support for NVMe multipath. - A fix for DM multipath path selectors (service-time and queue-length) to select paths in a more balanced way; largely academic but doesn't hurt. - Numerous DM raid target fixes and improvements. - Add a new DM "unstriped" target that enables Intel to workaround firmware limitations in some NVMe drives that are striped internally (this target also works when stacked above the DM "striped" target). - Various Documentation fixes and improvements. - Misc. cleanups and fixes across various DM infrastructure and targets (e.g. bufio, flakey, log-writes, snapshot). -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJacgwPAAoJEMUj8QotnQNaEw0H/0XRTcg8/lRuGl46kdeI3PgR ZxUy4XgUrCLiACWO5yCU/nKipB32+3xTlTDTBcjmaBfX8HolH147Pasb1KdHqLVC dOWLMpjlFztb5fnuOMitJA05qQAbgRlZ52QdVk/FDo9yWicgWjQZduh8aYX53pHw 6XOYWzSFAXQcaduPdz6TLiPw479xBwIpXxQbrO09f4qt3Ub4bqknEhzFXc+6M7zl ejmW/bG2Qg6WmsfAuaAhFTV0LpTPSEzvaq9TfR7yqFU3DvDIAi7Yh8eQinIUDo4u txpOGoESRAMPAMKH0/UJdr/u7jTsfgJox4QEavWfnViPvkouah5KdjVOL1veZ5U= =R3dN -----END PGP SIGNATURE----- Merge tag 'for-4.16/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - DM core fixes to ensure that bio submission follows a depth-first tree walk; this is critical to allow forward progress without the need to use the bioset's BIOSET_NEED_RESCUER. - Remove DM core's BIOSET_NEED_RESCUER based dm_offload infrastructure. - DM core cleanups and improvements to make bio-based DM more efficient (e.g. reduced memory footprint as well leveraging per-bio-data more). - Introduce new bio-based mode (DM_TYPE_NVME_BIO_BASED) that leverages the more direct IO submission path in the block layer; this mode is used by DM multipath and also optimizes targets like DM thin-pool that stack directly on NVMe data device. - DM multipath improvements to factor out legacy SCSI-only (e.g. scsi_dh) code paths to allow for more optimized support for NVMe multipath. - A fix for DM multipath path selectors (service-time and queue-length) to select paths in a more balanced way; largely academic but doesn't hurt. - Numerous DM raid target fixes and improvements. - Add a new DM "unstriped" target that enables Intel to workaround firmware limitations in some NVMe drives that are striped internally (this target also works when stacked above the DM "striped" target). - Various Documentation fixes and improvements. - Misc cleanups and fixes across various DM infrastructure and targets (e.g. bufio, flakey, log-writes, snapshot). * tag 'for-4.16/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: (69 commits) dm cache: Documentation: update default migration_throttling value dm mpath selector: more evenly distribute ties dm unstripe: fix target length versus number of stripes size check dm thin: fix trailing semicolon in __remap_and_issue_shared_cell dm table: fix NVMe bio-based dm_table_determine_type() validation dm: various cleanups to md->queue initialization code dm mpath: delay the retry of a request if the target responded as busy dm mpath: return DM_MAPIO_DELAY_REQUEUE if QUEUE_IO or PG_INIT_REQUIRED dm mpath: return DM_MAPIO_REQUEUE on blk-mq rq allocation failure dm log writes: fix max length used for kstrndup dm: backfill missing calls to mutex_destroy() dm snapshot: use mutex instead of rw_semaphore dm flakey: check for null arg_name in parse_features() dm thin: extend thinpool status format string with omitted fields dm thin: fixes in thin-provisioning.txt dm thin: document representation of <highest mapped sector> when there is none dm thin: fix documentation relative to low water mark threshold dm cache: be consistent in specifying sectors and SI units in cache.txt dm cache: delete obsoleted paragraph in cache.txt dm cache: fix grammar in cache-policies.txt ... |

Merge tag 'xfs-4.16-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull xfs updates from Darrick Wong:
"This merge cycle, we're again some substantive changes to XFS.
Metadata verifiers have been restructured to provide more detail about
which part of a metadata structure failed checks, and we've enhanced
the new online fsck feature to cross-reference extent allocation
information with the other metadata structures. With this pull, the
metadata verification part of online fsck is more or less finished,
though the feature is still experimental and still disabled by
default.
We're also preparing to remove the EXPERIMENTAL tag from a couple of
features this cycle. This week we're committing a bunch of space
accounting fixes for reflink and removing the EXPERIMENTAL tag from
reflink; I anticipate that we'll be ready to do the same for the
reverse mapping feature next week. (I don't have any pending fixes for
rmap; however I wish to remove the tags one at a time.)
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. Let me know if
there's any merge problems -- git merge reported that one of our
patches touched the same function as the i_version series, but it
resolved things cleanly.
Summary:
- Log faulting code locations when verifiers fail, for improved
diagnosis of corrupt filesystems.
- Implement metadata verifiers for local format inode fork data.
- Online scrub now cross-references metadata records with other
metadata.
- Refactor the fs geometry ioctl generation functions.

12. Andreas generalized the non-recursive truncate code so it can
take a range of values for punch_hole support.
13. Andreas introduced new PUNCH_HOLE support that take advantage
of the previous patches.
14. Andreas contributed a patch to add fallocate with PUNCH_HOLE.
15. Andreas fixed some typos in the comments.
16. Andreas added function gfs2_max_stuffed_size to replace a piece
of code that was needlessly repeated throughout GFS2.
17. Andreas made a minor cleanup to function gfs2_page_add_databufs.
18. Andreas got rid of function gfs2_log_header_in in preparation for
the new log header fields.
19. Andreas also fixed up some missing newlines in kernel messages.
20. Andy Price added a new field to resource groups to indicate where
the next one should be, to allow fsck.gfs2 to make better repairs.
21. Andy also added new rindex fields for consistency checking.
22. Andy added a crc field to resource group headers for consistency
checking.
23. I added a patch to reduce redundancy in functions common to
freeing dinodes.

can better track down journal corruption.
27. I added a patch to fix a minor comment typo.
28. I also added a patch to fix a BUG in an unlink error path.
29. Steve Whitehouse contributed a patch to fix an incorrect use
of the gfs2_blk2rgrpd function.

iversion: make inode_cmp_iversion{+raw} return bool instead of s64
As Linus points out:
The inode_cmp_iversion{+raw}() functions are pure and utter crap.
Why?
You say that they return 0/negative/positive, but they do so in a
completely broken manner. They return that ternary value as the
sequence number difference in a 's64', which means that if you
actually care about that ternary value, and do the *sane* thing that
the kernel-doc of the function implies is the right thing, you would
do
int cmp = inode_cmp_iversion(inode, old);
if (cmp < 0 ...
and as a result you get code that looks sane, but that doesn't
actually *WORK* right.
Since none of the callers actually care about the ternary value here,
convert the inode_cmp_iversion{+raw} functions to just return a boolean
value (false for matching, true for non-matching).
This matches the existing use of these functions just fine, and makes it
simple to convert them to return a ternary value in the future if we
grow callers that need it.
With this change we can also reimplement inode_cmp_iversion in a simpler
way using inode_peek_iversion.

f2fs-for-4.16-rc1
In this round, we've followed up to support some generic features such as
cgroup, block reservation, linking fscrypt_ops, delivering write_hints,
and some ioctls. And, we could fix some corner cases in terms of power-cut
recovery and subtle deadlocks.
Enhancement:
- bitmap operations to handle NAT blocks
- readahead to improve readdir speed
- switch to use fscrypt_*
- apply write hints for direct IO
- add reserve_root=%u,resuid=%u,resgid=%u to reserve blocks for root/uid/gid
- modify b_avail and b_free to consider root reserved blocks
- support cgroup writeback

Highlights include:
Stable bugfixes:
- Fix breakages in the nfsstat utility due to the inclusion of the NFSv4
LOOKUPP operation.
- Fix a NULL pointer dereference in nfs_idmap_prepare_pipe_upcall() due to
nfs_idmap_legacy_upcall() being called without an 'aux' parameter.
- Fix a refcount leak in the standard O_DIRECT error path.
- Fix a refcount leak in the pNFS O_DIRECT fallback to MDS path.
- Fix CPU latency issues with nfs_commit_release_pages()

- NFS: Fix a race between mmap() and O_DIRECT
Features:
- Support the statx() mask and query flags to enable optimisations when
the user is requesting only attributes that are already up to date in
the inode cache, or is specifying the AT_STATX_DONT_SYNC flag.
- Add a module alias for the SCSI pNFS layout type.
Bugfixes:
- Automounting when resolving a NFSv4 referral should preserve the RDMA
transport protocol settings.
- Various other RDMA bugfixes from Chuck.

Merge branch 'misc.poll' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull poll annotations from Al Viro: "This introduces a __bitwise type for POLL### bitmap, and propagates the annotations through the tree. Most of that stuff is as simple as 'make ->poll() instances return __poll_t and do the same to local variables used to hold the future return value'. Some of the obvious brainos found in process are fixed (e.g. POLLIN misspelled as POLL_IN). At that point the amount of sparse warnings is low and most of them are for genuine bugs - e.g. ->poll() instance deciding to return -EINVAL instead of a bitmap. I hadn't touched those in this series - it's large enough as it is. Another problem it has caught was eventpoll() ABI mess; select.c and eventpoll.c assumed that corresponding POLL### and EPOLL### were equal. That's true for some, but not all of them - EPOLL### are arch-independent, but POLL### are not. The last commit in this series separates userland POLL### values from the (now arch-independent) kernel-side ones, converting between them in the few places where they are copied to/from userland. AFAICS, this is the least disruptive fix preserving poll(2) ABI and making epoll() work on all architectures. As it is, it's simply broken on sparc - try to give it EPOLLWRNORM and it will trigger only on what would've triggered EPOLLWRBAND on other architectures. EPOLLWRBAND and EPOLLRDHUP, OTOH, are never triggered at all on sparc.

Merge branch 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull siginfo cleanups from Eric Biederman: "Long ago when 2.4 was just a testing release copy_siginfo_to_user was made to copy individual fields to userspace, possibly for efficiency and to ensure initialized values were not copied to userspace. Unfortunately the design was complex, it's assumptions unstated, and humans are fallible and so while it worked much of the time that design failed to ensure unitialized memory is not copied to userspace. This set of changes is part of a new design to clean up siginfo and simplify things, and hopefully make the siginfo handling robust enough that a simple inspection of the code can be made to ensure we don't copy any unitializied fields to userspace. The design is to unify struct siginfo and struct compat_siginfo into a single definition that is shared between all architectures so that anyone adding to the set of information shared with struct siginfo can see the whole picture. Hopefully ensuring all future si_code assignments are arch independent. The design is to unify copy_siginfo_to_user32 and copy_siginfo_from_user32 so that those function are complete and cope with all of the different cases documented in signinfo_layout. I don't think there was a single implementation of either of those functions that was complete and correct before my changes unified them. The design is to introduce a series of helpers including force_siginfo_fault that take the values that are needed in struct siginfo and build the siginfo structure for their callers. Ensuring struct siginfo is built correctly. The remaining work for 4.17 (unless someone thinks it is post -rc1 material) is to push usage of those helpers down into the architectures so that architecture specific code will not need to deal with the fiddly work of intializing struct siginfo, and then when struct siginfo is guaranteed to be fully initialized change copy siginfo_to_user into a simple wrapper around copy_to_user. Further there is work in progress on the issues that have been documented requires arch specific knowledge to sort out. The changes below fix or at least document all of the issues that have been found with siginfo generation. Then proceed to unify struct siginfo the 32 bit helpers that copy siginfo to and from userspace, and generally clean up anything that is not arch specific with regards to siginfo generation. It is a lot but with the unification you can of siginfo you can already see the code reduction in the kernel" * 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (45 commits) signal/memory-failure: Use force_sig_mceerr and send_sig_mceerr mm/memory_failure: Remove unused trapno from memory_failure signal/ptrace: Add force_sig_ptrace_errno_trap and use it where needed signal/powerpc: Remove unnecessary signal_code parameter of do_send_trap signal: Helpers for faults with specialized siginfo layouts signal: Add send_sig_fault and force_sig_fault signal: Replace memset(info,...) with clear_siginfo for clarity signal: Don't use structure initializers for struct siginfo signal/arm64: Better isolate the COMPAT_TASK portion of ptrace_hbptriggered ptrace: Use copy_siginfo in setsiginfo and getsiginfo signal: Unify and correct copy_siginfo_to_user32 signal: Remove the code to clear siginfo before calling copy_siginfo_from_user32 signal: Unify and correct copy_siginfo_from_user32 signal/blackfin: Remove pointless UID16_SIGINFO_COMPAT_NEEDED signal/blackfin: Move the blackfin specific si_codes to asm-generic/siginfo.h signal/tile: Move the tile specific si_codes to asm-generic/siginfo.h signal/frv: Move the frv specific si_codes to asm-generic/siginfo.h signal/ia64: Move the ia64 specific si_codes to asm-generic/siginfo.h signal/powerpc: Remove redefinition of NSIGTRAP on powerpc signal: Move addr_lsb into the _sigfault union for clarity ... |

Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull perf updates from Ingo Molnar:
"Kernel side changes:
- Clean up the x86 instruction decoder (Masami Hiramatsu)
- Add new uprobes optimization for PUSH instructions on x86 (Yonghong
Song)
- Add MSR_IA32_THERM_STATUS to the MSR events (Stephane Eranian)
- Fix misc bugs, update documentation, plus various cleanups (Jiri
Olsa)
There's a large number of tooling side improvements:
- Intel-PT/BTS improvements (Adrian Hunter)
- Numerous 'perf trace' improvements (Arnaldo Carvalho de Melo)
- Introduce an errno code to string facility (Hendrik Brueckner)
- Various build system improvements (Jiri Olsa)
- Add support for CoreSight trace decoding by making the perf tools
use the external openCSD (Mathieu Poirier, Tor Jeremiassen)
- Add ARM Statistical Profiling Extensions (SPE) support (Kim
Phillips)
- libtraceevent updates (Steven Rostedt)
- Intel vendor event JSON updates (Andi Kleen)
- Introduce 'perf report --mmaps' and 'perf report --tasks' to show
info present in 'perf.data' (Jiri Olsa, Arnaldo Carvalho de Melo)
- Add infrastructure to record first and last sample time to the
perf.data file header, so that when processing all samples in a
'perf record' session, such as when doing build-id processing, or
when specifically requesting that that info be recorded, use that
in 'perf report --time', that also got support for percent slices
in addition to absolute ones.
I.e. now it is possible to ask for the samples in the 10%-20% time
slice of a perf.data file (Jin Yao)
- Allow system wide 'perf stat --per-thread', sorting the result (Jin
Yao)
E.g.:
[root@jouet ~]# perf stat --per-thread --metrics IPC

Pull timer updates from Thomas Gleixner:
"The timer departement presents:
- A rather large rework of the hrtimer infrastructure which
introduces softirq based hrtimers to replace the spread of
hrtimer/tasklet combos which force the actual callback execution
into softirq context. The approach is completely different from the
initial implementation which you cursed at 10 years ago rightfully.
The softirq based timers have their own queues and there is no
nasty indirection and list reshuffling in the hard interrupt
anymore. This comes with conversion of some of the hrtimer/tasklet
users, the rest and the final removal of that horrible interface
will come towards the end of the merge window or go through the
relevant maintainer trees.
Note: The top commit merged the last minute bugfix for the 10 years
old CPU hotplug bug as I wanted to make sure that I fatfinger the
merge conflict resolution myself.

- cleanups: device freeing, removed some call indirections, redundant
bio_put/_get, unused parameters, refactorings and renames
- RCU list traversal fixups
- simplify mount callchain, remove recursing back when mounting a
subvolume

Merge tag 'iversion-v4.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/jlayton/linux
Pull inode->i_version rework from Jeff Layton:
"This pile of patches is a rework of the inode->i_version field. We
have traditionally incremented that field on every inode data or
metadata change. Typically this increment needs to be logged on disk
even when nothing else has changed, which is rather expensive.
It turns out though that none of the consumers of that field actually
require this behavior. The only real requirement for all of them is
that it be different iff the inode has changed since the last time the
field was checked.
Given that, we can optimize away most of the i_version increments and
avoid dirtying inode metadata when the only change is to the i_version
and no one is querying it. Queries of the i_version field are rather
rare, so we can help write performance under many common workloads.
This patch series converts existing accesses of the i_version field to
a new API, and then converts all of the in-kernel filesystems to use
it. The last patch in the series then converts the backend
implementation to a scheme that optimizes away a large portion of the
metadata updates when no one is looking at it.
In my own testing this series significantly helps performance with
small I/O sizes. I also got this email for Christmas this year from
the kernel test robot (a 244% r/w bandwidth improvement with XFS over
DAX, with 4k writes):
https://lkml.org/lkml/2017/12/25/8
A few of the earlier patches in this pile are also flowing to you via
other trees (mm, integrity, and nfsd trees in particular)".

Merge branch 'for-4.16/block' of git://git.kernel.dk/linux-block
Pull block updates from Jens Axboe:
"This is the main pull request for block IO related changes for the
4.16 kernel. Nothing major in this pull request, but a good amount of
improvements and fixes all over the map. This contains:
- BFQ improvements, fixes, and cleanups from Angelo, Chiara, and
Paolo.
- Support for SMR zones for deadline and mq-deadline from Damien and
Christoph.
- Set of fixes for bcache by way of Michael Lyle, including fixes
from himself, Kent, Rui, Tang, and Coly.
- Series from Matias for lightnvm with fixes from Hans Holmberg,
Javier, and Matias. Mostly centered around pblk, and the removing
rrpc 1.2 in preparation for supporting 2.0.
- A couple of NVMe pull requests from Christoph. Nothing major in
here, just fixes and cleanups, and support for command tracing from
Johannes.
- Support for blk-throttle for tracking reads and writes separately.
From Joseph Qi. A few cleanups/fixes also for blk-throttle from
Weiping.
- Series from Mike Snitzer that enables dm to register its queue more
logically, something that's alwways been problematic on dm since
it's a stacked device.
- Series from Ming cleaning up some of the bio accessor use, in
preparation for supporting multipage bvecs.
- Various fixes from Ming closing up holes around queue mapping and
quiescing.
- BSD partition fix from Richard Narron, fixing a problem where we
can't mount newer (10/11) FreeBSD partitions.
- Series from Tejun reworking blk-mq timeout handling. The previous
scheme relied on atomic bits, but it had races where we would think
a request had timed out if it to reused at the wrong time.
- null_blk now supports faking timeouts, to enable us to better
exercise and test that functionality separately. From me.
- Kill the separate atomic poll bit in the request struct. After
this, we don't use the atomic bits on blk-mq anymore at all. From
me.
- sgl_alloc/free helpers from Bart.
- Heavily contended tag case scalability improvement from me.
- Various little fixes and cleanups from Arnd, Bart, Corentin,
Douglas, Eryu, Goldwyn, and myself"
