Merge tag 'f2fs-for-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs updates from Jaegeuk Kim: "This round looks fairly small comparing to the previous updates and includes mostly minor bug fixes. Nevertheless, as we've still interested in improving the stability, Chao added some debugging methods to diagnoze subtle runtime inconsistency problem. Enhancements: - store all the corruption or failure reasons in superblock - detect meta inode, summary info, and block address inconsistency - increase the limit for reserve_root for low-end devices - add the number of compressed IO in iostat Bug fixes: - DIO write fix for zoned devices - do out-of-place writes for cold files - fix some stat updates (FS_CP_DATA_IO, dirty page count) - fix race condition on setting FI_NO_EXTENT flag - fix data races when freezing super - fix wrong continue condition check in GC - do not allow ATGC for LFS mode In addition, there're some code enhancement and clean-ups as usual" * tag 'f2fs-for-6.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (32 commits) f2fs: change to use atomic_t type form sbi.atomic_files f2fs: account swapfile inodes f2fs: allow direct read for zoned device f2fs: support recording errors into superblock f2fs: support recording stop_checkpoint reason into super_block f2fs: remove the unnecessary check in f2fs_xattr_fiemap f2fs: introduce cp_status sysfs entry f2fs: fix to detect corrupted meta ino f2fs: fix to account FS_CP_DATA_IO correctly f2fs: code clean and fix a type error f2fs: add "c_len" into trace_f2fs_update_extent_tree_range for compressed file f2fs: fix to do sanity check on summary info f2fs: port to vfs{g,u}id_t and associated helpers f2fs: fix to do sanity check on destination blkaddr during recovery f2fs: let FI_OPU_WRITE override FADVISE_COLD_BIT f2fs: fix race condition on setting FI_NO_EXTENT flag f2fs: remove redundant check in f2fs_sanity_check_cluster f2fs: add static init_idisk_time function to reduce the code f2fs: fix typo f2fs: fix wrong dirty page count when race between mmap and fallocate. ...
