+Subject: [PATCH] hostmem: Fix up free host_nodes list right after visited
+
+In host_memory_backend_get_host_nodes, we build host_nodes
+list and output it to v (a StringOutputVisitor) but forget
+to free the list. This fixes the memory leak.
+
+The memory leak stack:
+
+Direct leak of 32 byte(s) in 2 object(s) allocated from:
