jbd2_journal_write_metadata_buffer
It's more intuitive to use jh_in->b_frozen_data directly instead of
done_copy_out variable. Simply remove unneeded done_copy_out variable
and use b_frozen_data instead.

Add the __counted_by compiler attribute to the flexible array member
inodes to improve access bounds-checking via CONFIG_UBSAN_BOUNDS and
CONFIG_FORTIFY_SOURCE.
Remove the now obsolete comment on the count field.
In ext4_expand_inode_array(), use struct_size() instead of offsetof()
and remove the local variable count. Increment the count field before
adding a new inode to the inodes array.
Compile-tested only.

Function jbd2_journal_shrink_checkpoint_list() assumes that '0' is not a
valid value for transaction IDs, which is incorrect.
Furthermore, the sbi->s_fc_ineligible_tid handling also makes the same
assumption by being initialised to '0'. Fortunately, the sb flag
EXT4_MF_FC_INELIGIBLE can be used to check whether sbi->s_fc_ineligible_tid
has been previously set instead of comparing it with '0'.

jbd2_cleanup_journal_tail() (e.g., an EIO), we don't stop waiting for free
space right away, we try other branches, and if j_committing_transaction
is NULL (i.e., the tid is 0), we will get the following complain:

When a full journal commit is on-going, any fast commit has to be enqueued
into a different queue: FC_Q_STAGING instead of FC_Q_MAIN. This enqueueing
is done only once, i.e. if an inode is already queued in a previous fast
commit entry it won't be enqueued again. However, if a full commit starts
_after_ the inode is enqueued into FC_Q_MAIN, the next fast commit needs to
be done into FC_Q_STAGING. And this is not being done in function
ext4_fc_track_template().
This patch fixes the issue by re-enqueuing an inode into the STAGING queue
during the fast commit clean-up callback when doing a full commit. However,
to prevent a race with a fast-commit, the clean-up callback has to be called
with the journal locked.
This bug was found using fstest generic/047. This test creates several 32k
bytes files, sync'ing each of them after it's creation, and then shutting
down the filesystem. Some data may be loss in this operation; for example a
file may have it's size truncated to zero.

Syzbot has found an ODEBUG bug in ext4_fill_super
The del_timer_sync function cancels the s_err_report timer,
which reminds about filesystem errors daily. We should
guarantee the timer is no longer active before kfree(sbi).
When filesystem mounting fails, the flow goes to failed_mount3,
where an error occurs when ext4_stop_mmpd is called, causing
a read I/O failure. This triggers the ext4_handle_error function
that ultimately re-arms the timer,
leaving the s_err_report timer active before kfree(sbi) is called.
Fix the issue by canceling the s_err_report timer after calling ext4_stop_mmpd.

fuse_notify_store(), unlike fuse_do_readpage(), does not enable page
zeroing (because it can be used to change partial page contents).
So fuse_notify_store() must be more careful to fully initialize page
contents (including parts of the page that are beyond end-of-file)
before marking the page uptodate.
The current code can leave beyond-EOF page contents uninitialized, which
makes these uninitialized page contents visible to userspace via mmap().
This is an information leak, but only affects systems which do not
enable init-on-alloc (via CONFIG_INIT_ON_ALLOC_DEFAULT_ON=y or the
corresponding kernel command line parameter).

Pull i2c fixes from Wolfram Sang:
"I2C core fix replacing IS_ENABLED() with IS_REACHABLE()
For host drivers, there are two fixes:
- Tegra I2C Controller: Addresses a potential double-locking issue
during probe. ACPI devices are not IRQ-safe when invoking runtime
suspend and resume functions, so the irq_safe flag should not be
set.
- Qualcomm GENI I2C Controller: Fixes an oversight in the exit path
of the runtime_resume() function, which was missed in the previous
release"

- Check for presence of only 'attr' feature before scrubbing an inode's
attribute fork.
- Restore the behaviour of setting AIL thread to TASK_INTERRUPTIBLE for

datadev and rtdev both support fsdax access modes.

Pull bcachefs fixes from Kent OverstreetL
- New on disk format version, bcachefs_metadata_version_disk_accounting_inum
This adds one more disk accounting counter, which counts disk usage
and number of extents per inode number. This lets us track
fragmentation, for implementing defragmentation later, and it also
counts disk usage per inode in all snapshots, which will be a useful
thing to expose to users.
- One performance issue we've observed is threads spinning when they
should be waiting for dirty keys in the key cache to be flushed by
journal reclaim, so we now have hysteresis for the waiting thread, as
well as improving the tracepoint and a new time_stat, for tracking
time blocked waiting on key cache flushing.
... and various assorted smaller fixes.
