Pull f2fs updates from Jaegeuk Kim:
 "The main changes include converting major IO paths to use folio, and
  adding various knobs to control GC more flexibly for Zoned devices.

  In addition, there are several patches to address corner cases of
  atomic file operations and better support for file pinning on zoned
  device.

  Enhancement:
   - add knobs to tune foreground/background GCs for Zoned devices
   - convert IO paths to use folio
   - reduce expensive checkpoint trigger frequency
   - allow F2FS_IPU_NOCACHE for pinned file
   - forcibly migrate to secure space for zoned device file pinning
   - get rid of buffer_head use
   - add write priority option based on zone UFS
   - get rid of online repair on corrupted directory

  Bug fixes:
   - fix to don't panic system for no free segment fault injection
   - fix to don't set SB_RDONLY in f2fs_handle_critical_error()
   - avoid unused block when dio write in LFS mode
   - compress: don't redirty sparse cluster during {,de}compress
   - check discard support for conventional zones
   - atomic: prevent atomic file from being dirtied before commit
   - atomic: fix to check atomic_file in f2fs ioctl interfaces
   - atomic: fix to forbid dio in atomic_file
   - atomic: fix to truncate pagecache before on-disk metadata truncation
   - atomic: create COW inode from parent dentry
   - atomic: fix to avoid racing w/ GC
   - atomic: require FMODE_WRITE for atomic write ioctls
   - fix to wait page writeback before setting gcing flag
   - fix to avoid racing in between read and OPU dio write, dio completion
   - fix several potential integer overflows in file offsets and dir_block_index
   - fix to avoid use-after-free in f2fs_stop_gc_thread()

  As usual, there are several code clean-ups and refactorings"

f2fs: avoid unused block when dio write in LFS mode 2024-09-11T03:30:27+00:00 Daejun Park daejun7.park@samsung.com 2024-09-05T05:24:33+00:00 0638a3197c194bed837c157c3574685e36febc7b This patch addresses the problem that when using LFS mode, unused blocks may occur in f2fs_map_blocks() during block allocation for dio writes. If a new section is allocated during block allocation, it will not be included in the map struct by map_is_mergeable() if the LBA of the allocated block is not contiguous. However, the block already allocated in this process will remain unused due to the LFS mode. This patch avoids the possibility of unused blocks by escaping f2fs_map_blocks() when allocating the last block in a section.
