[PATCH 0/5] btrfs: qgroups rsv fixes

[Boris Burkov <boris@bur.io>]

This series contains a number of related but relatively orthogonal fixes
for various bugs in qgroup/squota reservation accounting. Most of these
manifest as either rsv underflow WARNINGs (in qgroup_rsv_release) or as
WARNINGs at umount for unreleased space.

With these fixes, I am able to get a fully clean '-g auto' fstests run
on my setup and with -O squota in MKFS_OPTIONS.

Boris Burkov (5):
  btrfs: free qgroup rsv on ioerr ordered_extent
  btrfs: fix qgroup_free_reserved_data int overflow
  btrfs: free qgroup pertrans rsv on trans abort
  btrfs: dont clear qgroup rsv bit in release_folio
  btrfs: ensure releasing squota rsv on head refs
