Filipe Manana e774a693b7 btrfs: use btrfs_record_snapshot_destroy() during rmdir ... [ Upstream commit 157501b046 ] We are setting the parent directory's last_unlink_trans directly which may result in a concurrent task starting to log the directory not see the update and therefore can log the directory after we removed a child directory which had a snapshot within instead of falling back to a transaction commit. Replaying such a log tree would result in a mount failure since we can't currently delete snapshots (and subvolumes) during log replay. This is the type of failure described in commit 1ec9a1ae1e ("Btrfs: fix unreplayable log after snapshot delete + parent dir fsync"). Fix this by using btrfs_record_snapshot_destroy() which updates the last_unlink_trans field while holding the inode's log_mutex lock.
