-Subject: [PATCH 4/5] Linux: lock the parent dentry for lookup_one_len()
-
-During review of the changes in Linux 4.5, it was noted that
-callers of lookup_one_len() are obligated to hold the i_mutex
-on the parent directory, though we do not currently do so.
-Take the lock around the call as needed.
-
-The only call to lookup_one_len() occurs in afs_linux_sillyrename(),
-so may workloads may not encounter this codepath.
