Test that a new snapshot created with qgroup inherit passed should mark qgroup numbers inconsistent. Such inconsistent flag is required to show that we need a qgroup rescan to make qgroup numbers correct again. This is unavoidable since snapshot creation with qgroup inherit acts as snapshot creation + qgroup relationship assign. See btrfs(5) for why such operation needs qgroup rescan. This test failed on current kernel, the fix is submitted to the btrfs mail list titled: "btrfs: qgroup: Mark qgroup inconsistent if we're inherting snapshot to a new qgroup" Signed-off-by: Qu Wenruo <wqu@suse.com> Reviewed-by: Filipe Manana <fdmanana@suse.com> Signed-off-by: Eryu Guan <guaneryu@gmail.com>
