From: "Dr. David Alan Gilbert" <dgilb...@redhat.com> This patch uses glib's g_auto mechanism to automatically free rcu_read_lock's at the end of the block. Given that humans have a habit of forgetting an error path somewhere it's best to leave it to the compiler.
In particular: https://bugzilla.redhat.com/show_bug.cgi?id=1746787 suggests we've forgotten an unlock case somewhere in the rdma migration code.
