+Subject: [PATCH 2/4] xfs: Fix termination loop for directory iteration
+
+Directory iteration used wrong position (sizeof wrong structure) for
+termination of iteration inside a directory block. Luckily the position
+ended up being wrong by just 1 byte and directory entries are larger so
+things worked out fine in practice. But fix the problem anyway.
