If anyone has any objections, please let me know. ------------------ [ Upstream commit 6f7de19ed3d4d3526ca5eca428009f97cf969c2f ] Commit ff3d27a048d9 ("btrfs: qgroup: Finish rescan when hit the last leaf of extent tree") added a new exit for rescan finish. However after finishing quota rescan, we set fs_info->qgroup_rescan_progress to (u64)-1 before we exit through the original exit path. While we missed that assignment of (u64)-1 in the new exit path. The end result is, the quota status item doesn't have the same value. (-1 vs the last bytenr + 1) Although it doesn't affect quota accounting, it's still better to keep the original behavior.
