From d5abe669172f20a4129a711de0f250a4e07db298 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Wed, 6 Dec 2006 20:37:26 -0800 Subject: [PATCH] debug: workqueue locking sanity Workqueue functions should not leak locks, assert so, printing the last function ran. Use macros in lockdep.h to avoid include dependency pains.
