From f29bc1b7316d5f58c74bac7fd516090e28dca840 Mon Sep 17 00:00:00 2001 From: Qu Wenruo Date: Wed, 27 Jun 2018 18:19:55 +0800 Subject: [PATCH] btrfs: quota: Set rescan progress to (u64)-1 if we hit last leaf commoit 6f7de19ed3d4d3526ca5eca428009f97cf969c2f upstream 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.
