f2fs: fix to do sanity check on extent cache correctly
The root cause is we applied both v1 and v2 of the patch, v2 is the right
fix, so it needs to revert v1 in order to fix reported issue.
v1:
commit d48a7b3a72f1 ("f2fs: fix to do sanity check on extent cache correctly")
https://lore.kernel.org/lkml/20230109034920.492914-1-chao@kernel.org/
v2:

The commit 25f9080576b9 ("f2fs: add async reset zone command support")
introduced "async reset zone commands" by calling
__submit_zone_reset_cmd() in async discard operations. However,
__submit_zone_reset_cmd() is called regardless of zone type of discard
target zone. When devices have conventional zones, zone reset commands
are sent to the conventional zones and cause I/O errors.
Avoid the I/O errors by checking that the discard target zone type is
sequential write required. If not, handle the discard operation in same
manner as non-zoned, regular block devices. For that purpose, add a new
helper function f2fs_bdev_index() which gets index of the zone reset
target device.

Compression option in inode should not be changed after they have

Thread A Thread B

Avoid such race condition by covering f2fs_file_mmap() w/ i_sem lock,
meanwhile add mmap file check condition in f2fs_may_compress() as well.

This reverts commit bfd476623999118d9c509cb0fa9380f2912bc225.
Shinichiro Kawasaki reported:
When I ran workloads on f2fs using v6.5-rcX with fixes [1][2] and a zoned block
devices with 4kb logical block size, I observe mount failure as follows. When
I revert this commit, the failure goes away.
[ 167.781975][ T1555] F2FS-fs (dm-0): IO Block Size: 4 KB
[ 167.890728][ T1555] F2FS-fs (dm-0): Found nat_bits in checkpoint
[ 171.482588][ T1555] F2FS-fs (dm-0): Zone without valid block has non-zero write pointer. Reset the write pointer: wp[0x1300,0x8]
[ 171.496000][ T1555] F2FS-fs (dm-0): (0) : Unaligned zone reset attempted (block 280000 + 80000)
[ 171.505037][ T1555] F2FS-fs (dm-0): Discard zone failed: (errno=-5)
The patch replaced "sbi->log_blocksize - SECTOR_SHIFT" with
"sbi->log_sectors_per_block". However, I think these two are not equal when the
device has 4k logical block size. The former uses Linux kernel sector size 512
byte. The latter use 512b sector size or 4kb sector size depending on the
device. mkfs.f2fs obtains logical block size via BLKSSZGET ioctl from the device
and reflects it to the value sbi->log_sector_size_per_block. This causes
unexpected write pointer calculations in check_zone_write_pointer(). This
resulted in unexpected zone reset and the mount failure.

We just sorted the entries and fields last release, so just out of a
perverse sense of curiosity, I decided to see if we can keep things
ordered for even just one release.
The answer is "No. No we cannot".
I suggest that all kernel developers will need weekly training sessions,
involving a lot of Big Bird and Sesame Street. And at the yearly
maintainer summit, we will all sing the alphabet song together.
I doubt I will keep doing this. At some point "perverse sense of
curiosity" turns into just a cold dark place filled with sadness and
despair.

On shutdown or kexec, the kernel tries to park the non-boot CPUs with

If the CPU which panics is not the boot CPU then it sends an INIT IPI

fork: lock VMAs of the parent process when forking
|
|
When forking a child process, the parent write-protects anonymous pages
and COW-shares them with the child being forked using copy_present_pte().
We must not take any concurrent page faults on the source vma's as they
are being processed, as we expect both the vma and the pte's behind it
to be stable. For example, the anon_vma_fork() expects the parents
vma->anon_vma to not change during the vma copy.
A concurrent page fault on a page newly marked read-only by the page
copy might trigger wp_page_copy() and a anon_vma_prepare(vma) on the
source vma, defeating the anon_vma_clone() that wasn't done because the
parent vma originally didn't have an anon_vma, but we now might end up
copying a pte entry for a page that has one.
Before the per-vma lock based changes, the mmap_lock guaranteed
exclusion with concurrent page faults. But now we need to do a
vma_start_write() to make sure no concurrent faults happen on this vma
while it is being processed.
This fix can potentially regress some fork-heavy workloads. Kernel
build time did not show noticeable regression on a 56-core machine while
a stress test mapping 10000 VMAs and forking 5000 times in a tight loop
shows ~5% regression. If such fork time regression is unacceptable,
disabling CONFIG_PER_VMA_LOCK should restore its performance. Further
optimizations are possible if this regression proves to be problematic.

mmap_region adds a newly created VMA into VMA tree and might modify it
afterwards before dropping the mmap_lock. This poses a problem for page
faults handled under per-VMA locks because they don't take the mmap_lock
and can stumble on this VMA while it's still being modified. Currently
this does not pose a problem since post-addition modifications are done
only for file-backed VMAs, which are not handled under per-VMA lock.
However, once support for handling file-backed page faults with per-VMA
locks is added, this will become a race.
Fix this by write-locking the VMA before inserting it into the VMA tree.
Other places where a new VMA is added into VMA tree do not modify it
after the insertion, so do not need the same locking.

With recent changes necessitating mmap_lock to be held for write while
expanding a stack, per-VMA locks should follow the same rules and be

The Smatch static checker reports the following warnings:
lib/dhry_run.c:38 dhry_benchmark() warn: sleeping in atomic context
lib/dhry_run.c:43 dhry_benchmark() warn: sleeping in atomic context
Indeed, dhry() does sleeping allocations inside the non-preemptable

Fix this by using atomic allocations instead.
Add error handling, as atomic these allocations may fail.

Commit 946fa0dbf2d8 ("mm/slub: extend redzone check to extra allocated
kmalloc space than requested") added precise kmalloc redzone poisoning to
the slub_debug functionality.
However, this commit didn't account for HW_TAGS KASAN fully initializing
the object via its built-in memory initialization feature. Even though
HW_TAGS KASAN memory initialization contains special memory initialization
handling for when slub_debug is enabled, it does not account for in-object
slub_debug redzones. As a result, HW_TAGS KASAN can overwrite these
redzones and cause false-positive slub_debug reports.
To fix the issue, avoid HW_TAGS KASAN memory initialization when
slub_debug is enabled altogether. Implement this by moving the
__slub_debug_enabled check to slab_post_alloc_hook. Common slab code
seems like a more appropriate place for a slub_debug check anyway.

Commit bb6e04a173f0 ("kasan: use internal prototypes matching gcc-13
builtins") introduced a bug into the memory_is_poisoned_n implementation:
it effectively removed the cast to a signed integer type after applying
KASAN_GRANULE_MASK.
As a result, KASAN started failing to properly check memset, memcpy, and
other similar functions.
Fix the bug by adding the cast back (through an additional signed integer
variable to make the code more readable).

Patch series "Update .mailmap for my work address and fix manpage".
While updating mailmap for the going-away address, I also found that on
current systems the manpage linked from the header comment changed.
And in fact it looks like the git mailmap feature got its own manpage.
This patch (of 2):
On recent systems the git-shortlog manpage only tells people to
See gitmailmap(5)
So instead of sending people on a scavenger hunt, put that info into the
header directly. Though keep the old reference around for older systems.

nr_to_write is a count of pages, so we need to decrease it by the number
of pages in the folio we just wrote, not by 1. Most callers specify
either LONG_MAX or 1, so are unaffected, but writeback_sb_inodes() might
end up writing 512x as many pages as it asked for.

That happens because a BUG() statement in huge_pte_alloc() attempts to
check that a pte, if present, is a hugetlb pte, but it does so in a
non-lockless-safe manner that leads to a false BUG() report.
We got here due to a couple of bugs, each of which by itself was not quite
enough to cause a problem:
First of all, before commit c33c794828f2("mm: ptep_get() conversion"), the
BUG() statement in huge_pte_alloc() was itself fragile: it relied upon
compiler behavior to only read the pte once, despite using it twice in the
same conditional.
Next, commit c33c794828f2 ("mm: ptep_get() conversion") broke that
delicate situation, by causing all direct pte reads to be done via
READ_ONCE(). And so READ_ONCE() got called twice within the same BUG()
conditional, leading to comparing (potentially, occasionally) different
versions of the pte, and thus to false BUG() reports.
Fix this by taking a single snapshot of the pte before using it in the
BUG conditional.
Now, that commit is only partially to blame here but, people doing
bisections will invariably land there, so this will help them find a fix
for a real crash. And also, the previous behavior was unlikely to ever
expose this bug--it was fragile, yet not actually broken.
So that's why I chose this commit for the Fixes tag, rather than the
commit that created the original BUG() statement.
