In this round, key enhancements focus on introducing a dedicated metadata
cache infrastructure and dynamically parameterizing on-disk block layouts
and geometry macros. Moving meta, node, and compress blocks out of the VFS
page cache removes the page == block size assumption for metadata, which
along with dynamic block layout descriptions paves the way for large folio
and page != block support in the future. We also opt in to multigrain
timestamps, add bio entry-count throttling for asynchronous write_end_io
completion, and expose the resizable_tail feature via sysfs.
Alongside these features, critical bug fixes resolve race conditions across
compression, mmap write faults, checkpoint/shutdown, and filesystem freeze,
prevent write bio splitting and GC holes on sequential zoned devices, and
strengthen on-disk sanity checks for SIT/NAT bitmaps, read-only curseg
entries, and device aliasing. Additional stability patches address online
resize, roll-forward recovery, atomic file operations, quota handling, and
dirty inode syncing livelocks.
Enhancement:
- implement dedicated metadata cache for meta, node, and compress blocks
to decouple metadata from page cache for large folio and page != block
support
- dynamically describe SIT, NAT, orphan, dentry, node, and xattr block
layouts and parameterize block/sector/node conversion macros
- opt in to multigrain timestamps
- introduce max_atc_write_bio_entry_cnt sysfs node
- expose resizable_tail feature via sysfs
- avoid unnecessary reads in f2fs_update_meta_block()
Bug fix:
- compress: force out-place update for all writes, allow pinning empty
compressed files, and fix truncate/writeback and cache population races
- zone: avoid bio split and GC target block grab failure on sequential zones
- quota: convert inline quota files on quotaon, fix flush failure during
freeze, and restore empty string mount options
- atomic/mmap: disallow mmap write and data-modifying fallocate on atomic
files, avoid truncate_inode_pages_final() on live inodes, and fix races in
f2fs_vm_page_mkwrite()
- resize/alias: refresh pinned allocation boundary and flush SIT journal
during resize, and drop pending discards before reserving device alias
- sanity check: bound SIT/NAT bitmaps by checkpoint pack, check all
cur_*_segno[] on readonly images, and validate multi-device on device alias
- recovery/cp: release removed xattr node in roll-forward recovery, invalidate
curseg on change_curseg() failure, and return -EIO for lost inode block
after cp_error
- fix livelock in syncing dirty inodes and preserve APPEND/UPDATE ino entries
- use bio_in_atomic() in f2fs_{read,write}_end_io()
- fix 32-bit shift truncation in mount option bitmasks and defragment range
And, the series includes a number of minor bug fixes.
