+Subject: [PATCH] bus/peer: fix catching OOM when linking match-rules
+
+When the match-rule infrastructure was extended to have per-key lookup
+tables, all call-sites had to be amended to catch errors when linking
+new rules. One such site was missed, so fix this and catch the error
+properly.
+
+The conversion was initially performed in:
+
+    commit 6c2b082522a6af033cd6699b669a4de614c41ad7
+    Author: Tom Gundersen <teg@jklm.no>
+    Date:   Wed Apr 25 17:16:47 2018 +0200
+
+        match: make match_rule_link() fallible
+
+This fixes a possible bug where ENOMEM is ignored and thus a match rule
+is silently dropped instead of being linked and retained.
