From a4c410f00f7ca4bd448b0d63f6f882fd244dc991 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Wed, 6 Dec 2006 20:37:21 -0800 Subject: [PATCH] lockdep: print current locks on in_atomic warnings Add debug_show_held_locks(current) to __might_sleep() and schedule(); this makes finding the offending lock leak easier.
