Merge tag 'f2fs-for-6.10.rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs

Pull f2fs updates from Jaegeuk Kim:
 "In this round, we've tried to address some performance issues on zoned
  storage such as direct IO and write_hints. In addition, we've migrated
  some IO paths using folio. Meanwhile, there are multiple bug fixes in
  the compression paths, sanity check conditions, and error handlers.

  Enhancements:
   - allow direct io of pinned files for zoned storage
   - assign the write hint per stream by default
   - convert read paths and test_writeback to folio
   - avoid allocating WARM_DATA segment for direct IO

  Bug fixes:
   - fix false alarm on invalid block address
   - fix to add missing iput() in gc_data_segment()
   - fix to release node block count in error path of
     f2fs_new_node_page()
   - compress:
       - don't allow unaligned truncation on released compress inode
       - cover {reserve,release}_compress_blocks() w/ cp_rwsem lock
       - fix error path of inc_valid_block_count()
       - fix to update i_compr_blocks correctly
   - fix block migration when section is not aligned to pow2
   - don't trigger OPU on pinfile for direct IO
   - fix to do sanity check on i_xattr_nid in sanity_check_inode()
   - write missing last sum blk of file pinning section
   - clear writeback when compression failed
   - fix to adjust appropirate defragment pg_end

  As usual, there are several minor code clean-ups, and fixes to manage
  missing corner cases in the error paths"
