From db5df254120004471e1c957957ab2f1e612dcbd6 Mon Sep 17 00:00:00 2001 From: Nikolay Borisov Date: Thu, 13 Jan 2022 17:16:18 +0200 Subject: [PATCH] btrfs: move QUOTA_ENABLED check to rescan_should_stop from btrfs_qgroup_rescan_worker Instead of having 2 places that short circuit the qgroup leaf scan have everything in the qgroup_rescan_leaf function. In addition to that, also ensure that the inconsistent qgroup flag is set when rescan_should_stop returns true. This both retains the old behavior when -EINTR was set in the body of the loop and at the same time also extends this behavior when scanning is interrupted due to remount or unmount operations.
