df65f1660b block/bdev.c: use the knowledge of inode/bdev coallocation
Here we know that bdevfs inodes are coallocated with struct block_device
and we can get to ->bd_inode value without any dereferencing.  Introduce
an inlined helper (static, *not* exported, purely internal for bdev.c)
that gets an associated inode by block_device - BD_INODE(bdev).

NOTE: leave it static; nobody outside of block/bdev.c has any business
playing with that.

2638c20876 missing helpers: bdev_unhash(), bdev_drop()
bdev_unhash(): make block device invisible to lookups by device number
bdev_drop(): drop reference to associated inode.

Both are internal, for use by genhd and partition-related code - similar
to bdev_add().  The logics in there (especially the lifetime-related
parts of it) ought to be cleaned up, but that's a separate story; here
we just encapsulate getting to associated inode.

559428a915 ext4: remove block_device_ejected()
block_device_ejected() is added by commit bdfe0cbd74 ("Revert
"ext4: remove block_device_ejected"") in 2015. At that time 'bdi->wb'
is destroyed synchronized from del_gendisk(), hence if ext4 is still
mounted, and then mark_buffer_dirty() will reference destroyed 'wb'.
However, such problem doesn't exist anymore:

- commit d03f6cdc1f ("block: Dynamically allocate and refcount
backing_dev_info") switch bdi to use refcounting;
- commit 13eec2363e ("fs: Get proper reference for s_bdi"), will grab
additional reference of bdi while mounting, so that 'bdi->wb' will not
be destroyed until generic_shutdown_super().

Hence remove this dead function block_device_ejected().

b85c42981a btrfs_get_bdev_and_sb(): call set_blocksize() only for exclusive opens
btrfs_get_bdev_and_sb() has two callers - btrfs_open_one_device(),
which asks for open to be exclusive and btrfs_get_dev_args_from_path(),
which doesn't.  Currently it does set_blocksize() in all cases.

I'm rather dubious about the need to do set_blocksize() anywhere in btrfs,
to be honest - there's some access to page cache of underlying block
devices in there, but it's nowhere near the hot paths, AFAICT.

In any case, btrfs_get_dev_args_from_path() only needs to read
the on-disk superblock and copy several fields out of it; all
callers are only interested in devices that are already opened
and brought into per-filesystem set, so setting the block size
is redundant for those and actively harmful if we are given
a pathname of unrelated device.

So we only need btrfs_get_bdev_and_sb() to call set_blocksize()
when it's asked to open exclusive.

3a52c03d1e pktcdvd: sort set_blocksize() calls out
1) it doesn't make any sense to have ->open() call set_blocksize() on the
device being opened - the caller will override that anyway.

2) setting block size on underlying device, OTOH, ought to be done when
we are opening it exclusive - i.e. as part of pkt_open_dev().  Having
it done at setup time doesn't guarantee us anything about the state
at the time we start talking to it.  Worse, if you happen to have
the underlying device containing e.g. ext2 with 4Kb blocks that
is currently mounted r/o, that set_blocksize() will confuse the hell
out of filesystem.

af63dd715a bcache_register(): don't bother with set_blocksize()
We are not using __bread() anymore and read_cache_page_gfp() doesn't
care about block size.  Moreover, we should *not* change block
size on a device that is currently held exclusive - filesystems
that use buffer cache expect the block numbers to be interpreted
in units set by filesystem.

 "Get rid of lockdep false positives around sysfs/overlayfs

  syzbot has uncovered a class of lockdep false positives for setups
  with sysfs being one of the backing layers in overlayfs. The root
  cause is that of->mutex allocated when opening a sysfs file read-only
  (which overlayfs might do) is confused with of->mutex of a file opened
  writable (held in write to sysfs file, which overlayfs won't do).

  Assigning them separate lockdep classes fixes that bunch and it's
  obviously safe"

  - Follow up x86 topology fixes.
 
 Note that there's minor cleanups included in the BHI fixes,
 which we'd normally delay to the next merge window, but the
 BHI mitigations code is new and will be backported widely,
 so we thought it would be better to have a unified codebase
 at this stage. (Let me know if that assumption is wrong and
 I'll rebase it.)

 - vhost has apparently been lacking an smp_rmb() -
   due to code duplication :( The duplication will be fixed in

16b52bbee4 kernfs: annotate different lockdep class for of->mutex of writable files
The writable file /sys/power/resume may call vfs lookup helpers for
arbitrary paths and readonly files can be read by overlayfs from vfs
helpers when sysfs is a lower layer of overalyfs.

To avoid a lockdep warning of circular dependency between overlayfs
inode lock and kernfs of->mutex, use a different lockdep class for
writable and readonly kernfs files.

c0297e7dd5 ata: libata-core: Allow command duration limits detection for ACS-4 drives
Even though the command duration limits (CDL) feature was first added
in ACS-5 (major version 12), there are some ACS-4 (major version 11)
drives that implement CDL as well.

IDENTIFY_DEVICE, SUPPORTED_CAPABILITIES, and CURRENT_SETTINGS log pages
are mandatory in the ACS-4 standard so it should be safe to read these
log pages on older drives implementing the ACS-4 standard.

7933650478 ata: libata-scsi: Fix ata_scsi_dev_rescan() error path
Commit 0c76106cb9 ("scsi: sd: Fix TCG OPAL unlock on system resume")
incorrectly handles failures of scsi_resume_device() in
ata_scsi_dev_rescan(), leading to a double call to
spin_unlock_irqrestore() to unlock a device port. Fix this by redefining
the goto labels used in case of errors and only unlock the port
scsi_scan_mutex when scsi_resume_device() fails.

Bug found with the Smatch static checker warning:

	drivers/ata/libata-scsi.c:4774 ata_scsi_dev_rescan()
	error: double unlocked 'ap->lock' (orig line 4757)

d5cf50dafc Kconfig: add some hidden tabs on purpose
Commit d96c36004e ("tracing: Fix FTRACE_RECORD_RECURSION_SIZE Kconfig
entry") removed a hidden tab because it apparently showed breakage in
some third-party kernel config parsing tool.

It wasn't clear what tool it was, but let's make sure it gets fixed.
Because if you can't parse tabs as whitespace, you should not be parsing
the kernel Kconfig files.

In fact, let's make such breakage more obvious than some esoteric ftrace
record size option.  If you can't parse tabs, you can't have page sizes.

Yes, tab-vs-space confusion is sadly a traditional Unix thing, and
'make' is famous for being broken in this regard.  But no, that does not
mean that it's ok.

I'd add more random tabs to our Kconfig files, but I don't want to make
things uglier than necessary.  But it *might* bbe necessary if it turns
out we see more of this kind of silly tooling.

5939d45155 Tracing fixes for 6.9:
- Fix the buffer_percent accounting as it is dependent on three variables:
   1) pages_read - number of subbuffers read
   2) pages_lost - number of subbuffers lost due to overwrite
   3) pages_touched - number of pages that a writer entered
   These three counters only increment, and to know how many active pages
   there are on the buffer at any given time, the pages_read and
   pages_lost are subtracted from pages_touched. But the pages touched
   was incremented whenever any writer went to the next subbuffer even
   if it wasn't the only one, so it was incremented more than it should
   be causing the counter for how many subbuffers currently have content
   incorrect, which caused the buffer_percent that holds waiters until
   the ring buffer is filled to a given percentage to wake up early.
 
 - Fix warning of unused functions when PERF_EVENTS is not configured in
 
 - Replace bad tab with space in Kconfig for FTRACE_RECORD_RECURSION_SIZE
 
 - Fix to some kerneldoc function comments in eventfs code.
