[PATCH 0/4] btrfs-progs: check: fix and refactor load_quota_info()

[Qu Wenruo <wqu@suse.com>]

The btrfs-check code of qgroup verification is pretty old, and there is
a long existing bug from day 1 that causes incorrect initial search
condition.

The first patch is to fix that bug.

Then the second one to reduce the memory usage of qgroup_count
structure.

The third one is to refactor load_quota_info() to follow the modern
standard and practice.

Finally add a test case as a regression test.

Qu Wenruo (4):
  btrfs-progs: check: fix the inverted condition to load qgroups
  btrfs-progs: check: remove unused qgroup_count::key
  btrfs-progs: check: refactor load_quota_info()
  btrfs-progs: fsck-tests: add a new test case for qgroup tree check
