Merge tag 'f2fs-for-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs update from Jaegeuk Kim: "In this round, we've mainly modified to support non-power-of-two zone size, which is not required for f2fs by design. In order to avoid arch dependency, we refactored the messy rb_entry structure shared across different extent_cache. In addition to the improvement, we've also fixed several subtle bugs and error cases. Enhancements: - support non-power-of-two zone size for zoned device - remove sharing the rb_entry structure in extent cache - refactor f2fs_gc to call checkpoint in urgent condition - support iopoll Bug fixes: - fix potential corruption when moving a directory - fix to avoid use-after-free for cached IPU bio - fix the folio private usage - avoid kernel warnings or panics in the cp_error case - fix to recover quota data correctly - fix some bugs in atomic operations - fix system crash due to lack of free space in LFS - fix null pointer panic in tracepoint in __replace_atomic_write_block - fix iostat lock protection - fix scheduling while atomic in decompression path - preserve direct write semantics when buffering is forced - fix to call f2fs_wait_on_page_writeback() in f2fs_write_raw_pages()" * tag 'f2fs-for-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (52 commits) f2fs: remove unnessary comment in __may_age_extent_tree f2fs: allocate node blocks for atomic write block replacement f2fs: use cow inode data when updating atomic write f2fs: remove power-of-two limitation of zoned device f2fs: allocate trace path buffer from names_cache f2fs: add has_enough_free_secs() f2fs: relax sanity check if checkpoint is corrupted f2fs: refactor f2fs_gc to call checkpoint in urgent condition f2fs: remove folio_detach_private() in .invalidate_folio and .release_folio f2fs: remove bulk remove_proc_entry() and unnecessary kobject_del() f2fs: support iopoll method f2fs: remove batched_trim_sections node description f2fs: fix to check return value of inc_valid_block_count() f2fs: fix to check return value of f2fs_do_truncate_blocks() f2fs: fix passing relative address when discard zones f2fs: fix potential corruption when moving a directory f2fs: add radix_tree_preload_end in error case f2fs: fix to recover quota data correctly f2fs: fix to check readonly condition correctly docs: f2fs: Correct instruction to disable checkpoint ...
