This bug is exposed by populating a high level qgroup, and then make it childless with old qgroup numbers, and finally do rescan. Normally rescan should zero out all qgroups' accounting number, but due to a kernel bug which won't mark childless qgroups dirty, their on-disk data is never updated, thus old numbers remain and cause qgroup corruption. Fixed by the following kernel patch: "btrfs: qgroup: Dirty all qgroups before rescan" [Eryu: removed useless _filter_xfs_io] Reported-by: Misono Tomohiro <misono.tomohiro@jp.fujitsu.com> Signed-off-by: Qu Wenruo <wqu@suse.com> Reviewed-by: Eryu Guan <guaneryu@gmail.com> Signed-off-by: Eryu Guan <guaneryu@gmail.com>
