From a09785a2414afb261d9f719d544742af4300df22 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Mon, 3 Jul 2006 00:25:12 -0700 Subject: [PATCH] lockdep: annotate af_unix locking Teach special (recursive) locking code to the lock validator. Also splits af_unix's sk_receive_queue.lock class from the other networking skb-queue locks. Has no effect on non-lockdep kernels.
