From e0fdace10e75dac67d906213b780ff1b1a4cc360 Mon Sep 17 00:00:00 2001 From: David Miller Date: Fri, 1 Aug 2008 01:11:22 -0700 Subject: debug_locks: set oops_in_progress if we will log messages. Otherwise lock debugging messages on runqueue locks can deadlock the system due to the wakeups performed by printk(). Signed-off-by: David S.
