+Subject: btrfs: fix lost error handling when replaying directory deletes
+
+From: Filipe Manana <fdmanana@suse.com>
+
+commit 10adb1152d957a4d570ad630f93a88bb961616c1 upstream.
+
+At replay_dir_deletes(), if find_dir_range() returns an error we break out
+of the main while loop and then assign a value of 0 (success) to the 'ret'
+variable, resulting in completely ignoring that an error happened. Fix
+that by jumping to the 'out' label when find_dir_range() returns an error
+(negative value).
