  f2fs: compress: don't overwrite populated compress cache entry (2026-10-26 15:34:50 +0000)

----------------------------------------------------------------
f2fs-for-7.4-rc1

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.
