  ext4: always drain queued discard work in ext4_mb_release() (2026-03-27 23:39:10 -0400)

----------------------------------------------------------------
Update the MAINTAINERS file to add reviewers for the ext4 file system

Add a test issue an ext4 warning (not a WARN_ON) if there are still
dirty pages attached to an evicted inode.

A lot of ext4 bug fixes including:
   * Fix a number of Syzkaller issues.
   * Fix memory leaks on error paths.
   * Replace some BUG and WARN with EFSCORRUPTED reporting.
   * Fix a potential crash when disabling discard via remount followed
     by an immediate unmount.  (Found by Sashiko)
   * Fix a corner case which could lead to allocating blocks for an
     indirect-mapped inode block numbers > 2**32.
   * Fix a race when reallocating a freed inode that could result in
     a deadlock.
   * Fix a user-after-free in update_super_work when racing with umount.
   * Fix build issues when trying to build ext4's kunit tests as a module
   * Fix a bug where ext4_split_extent_zeroout() could fail to pass
     back an error from ext4_ext_dirty().
   * Avoid allocating blocks from a corrupted block group in
     ext4_mb_find_by_goal().
   * Fix a percpu_counters list corruption BUG triggered by an
     ext4 extents kunit.
   * Fix a potetial crash caused by the fast commit flush path potentially
     accessing the jinode structure before it is fully initialized.
   * Fix fsync(2) in no-journal mode to make sure the dirtied inode is
     write to storage.
   * Fix a bug when in no-journal mode, when ext4 tries to avoid using
     recently deleted inodes, if lazy itable initialization is enabled,
     can lead to an unitialized inode getting skipped and triggering
     an e2fsck complaint.
   * Fix journal credit calculation when setting an xattr when both
     the encryption and ea_inode feeatures are enabled.
   * Fix corner cases which could result in stale xarray tags after
     writeback.
   * Fix generic/475 failures caused by ENOSPC errors while creating
     a symlink when the system crashes resulting to a file system
     inconsistency when replaying the fast commit journal.
