Date: Sun, 2 Mar 2014 19:42:53 +0100 From: Reiter Wolfgang <wr0112358@...il.com> To: Ingo Molnar <mingo@...hat.com>, Peter Zijlstra <peterz@...radead.org> Cc: linux-kernel@...r.kernel.org, Reiter Wolfgang <wr0112358@...il.com> Subject: [PATCH 1/1] sched/deadline: Fix regression in cpudl_find. When using CONFIG_FTRACE_SELFTEST=y and CONFIG_FTRACE_STARTUP_TEST=y best_cpu is -1 and passed to function cpumask_check which takes unsigned int. Fix order of test arguments to avoid oops. Regression was introduced in commit 82b95800b256205cff2eeab5bbd03430d2d0f20d.
