Linus Torvalds 1d1df41c5a f2fs-for-5.17-rc1
In this round, we've tried to address some performance issues in f2fs_checkpoint
 and direct IO flows. Also, there was a work to enhance the page cache management
 used for compression. Other than them, we've done typical work including sysfs,
 code clean-ups, tracepoint, sanity check, in addition to bug fixes on corner
 cases.
 
 Enhancement:
  - use iomap for direct IO
  - try to avoid lock contention to improve f2fs_ckpt speed
  - avoid unnecessary memory allocation in compression flow
  - POSIX_FADV_DONTNEED drops the page cache containing compression pages
  - add some sysfs entries (gc_urgent_high_remaining, pending_discard)
 
 Bug fix:
  - try not to expose unwritten blocks to user by DIO
    : this was added to avoid merge conflict; another patch is coming to address
      other missing case.
  - relax minor error condition for file pinning feature used in Android OTA
  - fix potential deadlock case in compression flow
  - should not truncate any block on pinned file
 
 In addition, we've done some code clean-ups and tracepoint/sanity check
 improvement.
