+Subject: Revert "configfs: fix a race in configfs_lookup()"
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+This reverts commit c709c7ca020a52ef6530733a9a5f014bd6b71937 which is
+commit c42dd069be8dfc9b2239a5c89e73bbd08ab35de0 upstream.
+
+It was backported incorrectly, and will come back later in a way that
+actually works.
