This hook is called only from __extent_writepage_io which is already
called only from the data page writeout path. So there is no need to
make an indirect call via extent_io_ops. This patch just removes the
callback definition, exports the callback function and calls it directly
at the only call site. Also give the function a more descriptive name.
No functional changes.

Enhance btrfs_verify_dev_extents() to remember previous checked dev
extents, so it can verify no dev extents can overlap.
Analysis from Hans:
"Imagine allocating a DATA|DUP chunk.
In the chunk allocator, we first set...
max_stripe_size = SZ_1G;
max_chunk_size = BTRFS_MAX_DATA_CHUNK_SIZE
... which is 10GiB.
Then...
/* we don't want a chunk larger than 10% of writeable space */
max_chunk_size = min(div_factor(fs_devices->total_rw_bytes, 1),
max_chunk_size);
Imagine we only have one 7880MiB block device in this filesystem. Now
max_chunk_size is down to 788MiB.
The next step in the code is to search for max_stripe_size * dev_stripes
amount of free space on the device, which is in our example 1GiB * 2 =
2GiB. Imagine the device has exactly 1578MiB free in one contiguous
piece. This amount of bytes will be put in devices_info[ndevs - 1].max_avail
Next we recalculate the stripe_size (which is actually the device extent
length), based on the actual maximum amount of available raw disk space:
stripe_size = div_u64(devices_info[ndevs - 1].max_avail, dev_stripes);
stripe_size is now 789MiB
Next we do...
data_stripes = num_stripes / ncopies
...where data_stripes ends up as 1, because num_stripes is 2 (the amount
of device extents we're going to have), and DUP has ncopies 2.
Next there's a check...
if (stripe_size * data_stripes > max_chunk_size)
...which matches because 789MiB * 1 > 788MiB.
We go into the if code, and next is...
stripe_size = div_u64(max_chunk_size, data_stripes);
...which resets stripe_size to max_chunk_size: 788MiB
Next is a fun one...
/* bump the answer up to a 16MB boundary */
stripe_size = round_up(stripe_size, SZ_16M);
...which changes stripe_size from 788MiB to 800MiB.
We're not done changing stripe_size yet...
/* But don't go higher than the limits we found while searching
* for free extents
*/
stripe_size = min(devices_info[ndevs - 1].max_avail,
stripe_size);
This is bad. max_avail is twice the stripe_size (we need to fit 2 device
extents on the same device for DUP).
The result here is that 800MiB < 1578MiB, so it's unchanged. However,
the resulting DUP chunk will need 1600MiB disk space, which isn't there,
and the second dev_extent might extend into the next thing (next
dev_extent? end of device?) for 22MiB.
The last shown line of code relies on a situation where there's twice
the value of stripe_size present as value for the variable stripe_size
when it's DUP. This was actually the case before commit 92e222df7b
"btrfs: alloc_chunk: fix DUP stripe size handling", from which I quote:
"[...] in the meantime there's a check to see if the stripe_size does
not exceed max_chunk_size. Since during this check stripe_size is twice
the amount as intended, the check will reduce the stripe_size to
max_chunk_size if the actual correct to be used stripe_size is more than
half the amount of max_chunk_size."
In the previous version of the code, the 16MiB alignment (why is this
done, by the way?) would result in a 50% chance that it would actually
do an 8MiB alignment for the individual dev_extents, since it was
operating on double the size. Does this matter?
Does it matter that stripe_size can be set to anything which is not
16MiB aligned because of the amount of remaining available disk space
which is just taken?
What is the main purpose of this round_up?
The most straightforward thing to do seems something like...
stripe_size = min(
div_u64(devices_info[ndevs - 1].max_avail, dev_stripes),
stripe_size
)
..just putting half of the max_avail into stripe_size."

We have a complex loop design for find_free_extent(), that has different
behavior for each loop, some even includes new chunk allocation.
Instead of putting such a long code into find_free_extent() and makes it
harder to read, just extract them into find_free_extent_update_loop().
With all the cleanups, the main find_free_extent() should be pretty
barebone:
find_free_extent()
|- Iterate through all block groups
| |- Get a valid block group
| |- Try to do clustered allocation in that block group
| |- Try to do unclustered allocation in that block group
| |- Check if the result is valid
| | |- If valid, then exit
| |- Jump to next block group
|
|- Push harder to find free extents
|- If not found, re-iterate all block groups

mm/sparse: add common helper to mark all memblocks present
mm: introduce common STRUCT_PAGE_MAX_SHIFT define
alpha: fix hang caused by the bootmem removal
The spdxcheck script currently falls over when confronted with a binary
file (such as Documentation/logo.gif). To avoid that, always open files
in binary mode and decode line-by-line, ignoring encoding errors.
One tricky case is when piping data into the script and reading it from
standard input. By default, standard input will be opened in text mode,
so we need to reopen it in binary mode.
The breakage only happens with python3 and results in a
UnicodeDecodeError (according to Uwe).

migrate_page_move_mapping() expects pages with private data set to have
a page_count elevated by 1. This is what used to happen for xfs through
the buffer_heads code before the switch to iomap in commit 82cb14175e
("xfs: add support for sub-pagesize writeback without buffer_heads").
Not having the count elevated causes move_pages() to fail on memory
mapped files coming from xfs.
Make iomap compatible with the migrate_page_move_mapping() assumption by
elevating the page count as part of iomap_page_create() and lowering it
in iomap_page_release().
It causes the move_pages() syscall to misbehave on memory mapped files
from xfs. It does not not move any pages, which I suppose is "just" a
perf issue, but it also ends up returning a positive number which is out
of spec for the syscall. Talking to Michal Hocko, it sounds like
returning positive numbers might be a necessary update to move_pages()
anyway though
(https://lkml.kernel.org/r/20181116114955.GJ14706@dhcp22.suse.cz).
I only hit this in tests that verify that move_pages() actually moved
the pages. The test also got confused by the positive return from
move_pages() (it got treated as a success as positive numbers were not
expected and not handled) making it a bit harder to track down what's
going on.

The conversion of alpha to memblock as the early memory manager caused
boot to hang as described at [1].
The issue is caused because for CONFIG_DISCTONTIGMEM=y case,
memblock_add() is called using memory start PFN that had been rounded
down to the nearest 8Mb and it caused memblock to see more memory that
is actually present in the system.
Besides, memblock allocates memory from high addresses while bootmem was
using low memory, which broke the assumption that early allocations are
always accessible by the hardware.
This patch ensures that memblock_add() is using the correct PFN for the
memory start and forces memblock to use bottom-up allocations.

arm64: dma-mapping: Fix FORCE_CONTIGUOUS buffer clearing
One notable fix for our change to split pt_regs between user/kernel, we forgot
to update BPF to use the user-visible type which was an ABI break for BPF
programs.
A slightly ugly but minimal fix to do_syscall_trace_enter() so that we use
tracehook_report_syscall_entry() properly. We'll rework the code in next to
avoid the empty if body.
Seven commits fixing bugs in the new papr_scm (Storage Class Memory) driver.
The driver was finally able to be tested on the other hypervisor which exposed
several bugs. The fixes are all fairly minimal at least.
Fix a crash in our MSI code if an MSI-capable device is plugged into a non-MSI
capable PHB, only seen on older hardware (MPC8378).
Fix our legacy serial code to look for "stdout-path" since the device trees were
updated to use that instead of "linux,stdout-path".
A change to the COFF zImage code to fix booting old powermacs.
A couple of minor build fixes.

Pull drm fixes from Dave Airlie:
"While I hoped things would calm down, the world hasn't joined with me,
but it's a few things scattered over a wide area. The i915 workarounds
regression fix is probably the largest, the rest are more usual sized.
We also get some new AMD PCI IDs.
There is also a patch in here to MAINTAINERS to added Daniel as an
official DRM toplevel co-maintainer, he's decided he wants to step up
and share the glory, and he'll likely process next weeks fixes while
I'm away on holidays.
Summary:
amdgpu:
- some new PCI IDs
- fixed firmware image updates
- power management fixes
- locking warning fix
nouveau:
- framebuffer flushing fix
- memory leak fix
- tegra device init regression fix
vmwgfx:
- OOM kernel memory fix
- excess return in function fix
i915:
- the biggest fix is a regression fix where workarounds weren't
getting reapplied after a gpu hang causing further crashing, this
fixes the workaround application to make it happen again
- GPU hang fixes for Braswell and some GEN3 GPUs
- GVT fix for broadwell tiling
rockchip:
- revert to fix a regression causing a WARN on shutdown

- avoid crash attaching to non-existant bridges"

With the new validation code, a malicious user-space app could
potentially submit command streams with enough buffer-object and resource
references in them to have the resulting allocated validion nodes and
relocations make the kernel run out of GFP_KERNEL memory.
Protect from this by having the validation code reserve TTM graphics
memory when allocating.

- Fix bio-based DM core's dm_make_request() to properly impose device
limits on individual bios by making use of blk_queue_split().
- Fix long-standing race with how DM thinp notified userspace of
thin-pool mode state changes before they were actually made.
- Fix the zoned target's bio completion handling; this is a fairly
invassive fix at this stage but it is localized to the zoned target.
Any zoned target users will benefit from this fix.

lkml and Linus gained a CoC, and it's serious this time. Which means
my no 1 reason for declining to officially step up as drm maintainer
is gone, and I didn't find any new good excuse.
I chatted with a few people in private already, and the biggest
concern is that I mislay my community hat and start running around
with my intel hat only. Or some other convenient abuse of trust.
That's why this patch doesn't just need a lot of acks that mean "yeah
seems fine to me", but a lot of acks that mean "yeah we'll tell you
when you're over the line and usurp you from that comfy chair if you
don't get it". Which I think we've been done a fairly good job here at
dri-devel in general, but better to be clear.
Rough idea is that I'll do this for maybe 2-3 years, helping Dave
figure out a group model for drm overall. And getting the tooling and
infrastructure for that off the ground. Then step down again because
some other shiny thing that needs chasing. Of course as plans tend to
do, this one will probably pan out a bit different in reality.
