From 9127d4b1d9b2e8fba8e7fbc7f88ea93e5eb01396 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Fri, 22 Dec 2006 01:08:52 -0800 Subject: [PATCH] lock debugging: fix DEBUG_LOCKS_WARN_ON() & debug_locks_silent Matthew Wilcox noticed that the debug_locks_silent use should be inverted in DEBUG_LOCKS_WARN_ON(). This bug was causing spurious stacktraces and incorrect failures in the locking self-test on the parisc kernel.
