[PATCH 0/4] btrfs-progs: cmds/qgroup: enhance stale qgroups handling

[Qu Wenruo <wqu@suse.com>]

Currently the `<stale>` label is give incorrectly for a lot of qgroups
that can not and should not be deleted.

The patchset would address the problem for `btrfs qgroup show` and
`btrfs qgroup clear-stale` commands, so that:

- `clear-stale` would not try to delete incorrect qgroups
  Thus it should not return false errors.

- `show` would show extra types of qgroups
  Including `<under deletion>` and `<squota space holder>`

Qu Wenruo (4):
  btrfs-progs: cmds/qgroup: sync the fs before doing qgroup search
  btrfs-progs: cmds/qgroup: add qgroup_lookup::flags member
  btrfs-progs: cmds/qgroup: handle stale qgroup deleteion more
    accurately
  btrfs-progs: cmds/qgroup: add more special status for qgroups
