+Subject: [PATCH 1/1] libmultipath: ignore multipaths sections without wwid
+ option
+
+"multipathd show config local" was crashing in find_mp_by_wwid() if
+the multipath configuration included a multipaths section that did
+not set a wwid option. There is no reason to keep a mpentry that
+didn't set its wwid. Remove it in merge_mptable().

+Subject: [PATCH 1/1] libmultipath: check for null wwid before strcmp
+
+Commit 749aabd0 (libmultipath: ignore multipaths sections without wwid
+option) removed all mpentries with a NULL wwid, but didn't stop strcmp()
+from being run on them in merge_mptable(). The result of strcmp() with
+a NULL parameter is undefined, so fix that.
