+Subject: reiserfs: fix "new_insert_key may be used uninitialized ..."
+
+From: Jeff Mahoney <jeffm@suse.com>
+
+commit 0a11b9aae49adf1f952427ef1a1d9e793dd6ffb6 upstream.
+
+new_insert_key only makes any sense when it's associated with a
+new_insert_ptr, which is initialized to NULL and changed to a
+buffer_head when we also initialize new_insert_key.  We can key off of
+that to avoid the uninitialized warning.
