[GIT PULL] f2fs update for 6.2-rc1

[Jaegeuk Kim <jaegeuk@kernel.org>]

Hi Linus,

Could you please consider this pull request?

Note that, since I attached Reviewed-by to some recent committed patches, they
show quite new in the git log, but have been soaked in linux-next for a while.
In addition, one patch on top of the tree is still quite new, but it should be
a low risk of change. Hence, I added.

The following changes since commit bbb8ceb5e2421184db9560e9d2cfaf858e1db616:

  Merge tag 'v6.1-p2' of git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6 (2022-10-17 10:20:04 -0700)

  f2fs: reset wait_ms to default if any of the victims have been selected (2022-12-12 15:18:36 -0800)

----------------------------------------------------------------
f2fs-for-6.2-rc1

In this round, we've added two features: 1) F2FS_IOC_START_ATOMIC_REPLACE and
2) per-block age-based extent cache. 1) is a variant of the previous atomic
write feature which guarantees a per-file atomicity. It would be more efficient
than AtomicFile implementation in Android framework. 2) implements another type
of extent cache in memory which keeps the per-block age in a file, so that block
allocator could split the hot and cold data blocks more accurately.

Enhancement:
 - introduce F2FS_IOC_START_ATOMIC_REPLACE
 - refactor extent_cache to add a new per-block-age-based extent cache support
 - introduce discard_urgent_util, gc_mode, max_ordered_discard sysfs knobs
 - add proc entry to show discard_plist info
 - optimize iteration over sparse directories
 - add barrier mount option

Bug fix
 - avoid victim selection from previous victim section
 - fix to enable compress for newly created file if extension matches
 - set zstd compress level correctly
 - initialize locks early in f2fs_fill_super() to fix bugs reported by syzbot
 - correct i_size change for atomic writes
 - allow to read node block after shutdown
 - allow to set compression for inlined file
 - fix gc mode when gc_urgent_high_remaining is 1
 - should put a page when checking the summary info

Minor fixes and various clean-ups in GC, discard, debugfs, sysfs, and doc.
