Linus Torvalds 041fae9c10 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.
