Merge tag 'f2fs-for-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs

Pull f2fs updates from Jaegeuk Kim:
 "In this cycle, we've mainly investigated the zoned block device
  support along with patches such as correcting write pointers between
  f2fs and storage, adding asynchronous zone reset flow, and managing
  the number of open zones.

  Other than them, f2fs adds another mount option, "errors=x" to specify
  how to handle when it detects an unexpected behavior at runtime.

  Enhancements:
   - support 'errors=remount-ro|continue|panic' mount option
   - enforce some inode flag policies
   - allow .tmp compression given extensions
   - add some ioctls to manage the f2fs compression
   - improve looped node chain flow
   - avoid issuing small-sized discard commands during checkpoint
   - implement an asynchronous zone reset

  Bug fixes:
   - fix deadlock in xattr and inode page lock
   - fix and add sanity check in some error paths
   - fix to avoid NULL pointer dereference f2fs_write_end_io() along
     with put_super
   - set proper flags to quota files
   - fix potential deadlock due to unpaired node_write lock use
   - fix over-estimating free section during FG GC
   - fix the wrong condition to determine atomic context

  As usual, also there are a number of patches with code refactoring and
  minor clean-ups"
