if an inode backpointer points to a dirent that doesn't point back,
that's an error we should warn about.

If the reader acquires the read lock and then the writer enters the slow
path, while the reader proceeds to the unlock path, the following scenario
can occur without the change:
writer: pcpu_read_count(lock) return 1 (so __do_six_trylock will return 0)
reader: this_cpu_dec(*lock->readers)
reader: smp_mb()
reader: state = atomic_read(&lock->state) (there is no waiting flag set)
writer: six_set_bitmask()
then the writer will sleep forever.

Add a filesystem flag to indicate whether we did a clean recovery -
using c->sb.clean after we've got rw is incorrect, since c->sb is
updated whenever we write the superblock.

We had a bug where disk accounting keys didn't always have their version
field set in journal replay; change the BUG_ON() to a WARN(), and
exclude this case since it's now checked for elsewhere (in the bkey
validate function).

This was added to avoid double-counting accounting keys in journal
replay. But applied incorrectly (easily done since it applies to the
transaction commit, not a particular update), it leads to skipping
in-mem accounting for real accounting updates, and failure to give them
a version number - which leads to journal replay becoming very confused
the next time around.

Previously, check_inode() would delete unlinked inodes if they weren't
on the deleted list - this code dating from before there was a deleted
list.
But, if we crash during a logged op (truncate or finsert/fcollapse) of
an unlinked file, logged op resume will get confused if the inode has
already been deleted - instead, just add it to the deleted list if it
needs to be there; delete_dead_inodes runs after logged op resume.

__bch2_fsck_err() warns if the current task has a btree_trans object and
it wasn't passed in, because if it has to prompt for user input it has
to be able to unlock it.
But plumbing the btree_trans through bkey_validate(), as well as
transaction restarts, is problematic - so instead make bkey fsck errors
FSCK_AUTOFIX, which doesn't need to warn.

accounting read was checking if accounting replicas entries were marked
in the superblock prior to applying accounting from the journal,
which meant that a recently removed device could spuriously trigger a
"not marked in superblocked" error (when journal entries zero out the
offending counter).

Dealing with outside state within a btree transaction is always tricky.
check_extents() and check_dirents() have to accumulate counters for
i_sectors and i_nlink (for subdirectories). There were two bugs:
- transaction commit may return a restart; therefore we have to commit
before accumulating to those counters
- get_inode_all_snapshots() may return a transaction restart, before
updating w->last_pos; then, on the restart,
check_i_sectors()/check_subdir_count() would see inodes that were not
for w->last_pos

syzbot reported a null ptr deref in __copy_user [0]
In __bch2_read_super, when a corrupt backup superblock matches the
default opts offset, no error is assigned to ret and the freed superblock
gets through, possibly being assigned as the best sb in bch2_fs_open and
being later dereferenced, causing a fault. Assign EINVALID to ret when

Zero-initialize part of allocated bounce buffer which wasn't touched by
subsequent bch2_key_sort_fix_overlapping to mitigate later uinit-value
use KMSAN bug[1].
After applying the patch reproducer still triggers stack overflow[2] but
it seems unrelated to the uninit-value use warning. After further
investigation it was found that stack overflow occurs because KMSAN adds
too many function calls[3]. Backtrace of where the stack magic number gets
smashed was added as a reply to syzkaller thread[3].
It was confirmed that task's stack magic number gets smashed after the code
path where KSMAN detects uninit-value use is executed, so it can be assumed
that it doesn't contribute in any way to uninit-value use detection.

The values of the variables xres and yres are placed in strbuf.
These variables are obtained from strbuf1.
The strbuf1 array contains digit characters
and a space if the array contains non-digit characters.
Then, when executing sprintf(strbuf, "%ux%ux8", xres, yres);
more than 16 bytes will be written to strbuf.
It is suggested to increase the size of the strbuf array to 24.

"One bugfix patch, one preparation patch, and one conversion patch.
TOMOYO is useful as an analysis tool for learning how a Linux system

https://master.dl.sourceforge.net/project/tomoyo/docs/nsf2003-en.pdf/nsf2003-en.pdf?viasf=1
Although that attempt failed due to mapping problem between inode and
pathname, TOMOYO remains as an access restriction tool due to ability
to write custom policy by individuals.
I was delivering pure LKM version of TOMOYO (named AKARI) to users who
cannot afford rebuilding their distro kernels with TOMOYO enabled. But
since the LSM framework was converted to static calls, it became more
difficult to deliver AKARI to such users. Therefore, I decided to

- Preserve the CDAT access_coordinate from an endpoint
- Add the support for shared upstream link access_coordinate calculation
- Add documentation to explain how the calculations are done
Remove locking from memory notifier callback.

Pull sh updates from John Paul Adrian Glaubitz:
"The first change by Gaosheng Cui removes unused declarations which
have been obsoleted since commit 5a4053b23262 ("sh: Kill off dead
boards.") and the second by his colleague Hongbo Li replaces the use
of the unsafe simple_strtoul() with the safer kstrtoul() function in
the sh interrupt controller driver code"

sh: intc: Replace simple_strtoul() with kstrtoul()

I2C host fixes for v6.12-rc1
The DesignWare driver now has the correct ENABLE-ABORT sequence,
ensuring ABORT can always be sent when needed.
In the SynQuacer controller we now check for PCLK as an optional
clock, allowing ACPI to directly provide the clock rate.
The recent KEBA driver required a dependency fix in Kconfig.
The XIIC driver now has a corrected power suspend sequence.

Pull more xen updates from Juergen Gross:
"A second round of Xen related changes and features:
- a small fix of the xen-pciback driver for a warning issued by
sparse
- support PCI passthrough when using a PVH dom0
- enable loading the kernel in PVH mode at arbitrary addresses,
avoiding conflicts with the memory map when running as a Xen dom0
using the host memory layout"

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH:
"Here is a small set of patches for the driver core code for 6.12-rc1.
This set is the one that caused the most delay on my side, due to lots
of last-minute reports of problems in the async shutdown feature that
was added. In the end, I've reverted all of the patches in that series
so we are back to "normal" and the patch set is being reworked for the
next merge window.
Other than the async shutdown patches that were reverted, included in
here are:
- minor driver core cleanups
- minor driver core bus and class api cleanups and simplifications
for some callbacks
- some const markings of structures
- other even more minor cleanups
All of these, including the last minute reverts, have been in
linux-next, but all of the reports of problems in linux-next were
before the reverts happened. After the reverts, all is good"

The warning
Documentation/virt/kvm/locking.rst:31: ERROR: Unexpected indentation.
is caused by incorrectly treating a line as the continuation of a paragraph,
rather than as the first line in a bullet list.
