Code Issues Releases Wiki Activity

f2fs update for 6.10-rc1 

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.
 
 Enhancement:
  - 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 fix:
  - 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
  - compress: fix to cover {reserve,release}_compress_blocks() w/ cp_rwsem lock
  - compress: fix error path of inc_valid_block_count()
  - compress: 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.
