  f2fs: support resizable tail section and unify pinned allocation (2026-08-27 04:47:36 +0000)

----------------------------------------------------------------
f2fs-for-7.3-rc1

In this round, key enhancements focus on reducing inode management memory
overhead, introducing resizable tail sections with unified pinned allocation,
and boosting I/O throughput via parallel multi-device flushes and asynchronous
f2fs_write_end_io() execution. We also add dynamic device alias reservations to
allow on-the-fly space donation from user partitions.

Alongside these features, critical bug fixes resolve folio race conditions,
lingering dirty flags, dentry and block counter leaks, and potential deadloops
in f2fs_fsync_node_pages(). Additional stability patches address error-path
handling across symlink, sync, and rename/unlink operations, prevent pinned file
fragmentation, and correct segment migration and free section accounting in
free_segment_range.

Enhancement:
 - reduce memory footprint of ino management
 - support dynamic reserve/release for device aliasing
 - issue multi-device flushes in parallel
 - add a way to run f2fs_write_end_io() asynchronously
 - support resizable tail section and unify pinned allocation

Bug fix:
 - fix to pass folio->index to f2fs_sanity_check_node_footer()
 - fix folio_nr_pages() race after put in large folio invalidate
 - fix to clear dirty flag on folio in error path
 - accurately adjust free_sections during free_segment_range
 - fix to avoid potential deadloop in f2fs_fsync_node_pages()
 - fix the error path in symlink, device alias in rename/unlink,
   f2fs_sync_fs,
 - fix to migrate all curseg types during free_segment_range
 - fix to avoid pinfile fragment on fragment:{block, segment} mode
 - fix valid block count leak on data block allocation failure
 - fix dentry folio leak in find_in_level
 - reject overlapping move range after len expansion
 - fix some bugs related to file pinning, GC functions, i_size.

And, the series includes a number of minor bug fixes.
