Date: Tue, 29 Nov 2011 11:03:56 +0800 From: Shan Hai <haishan.bai@...il.com> To: linux-kernel@...r.kernel.org Cc: peterz@...radead.org, mingo@...e.hu, tglx@...utronix.de, Shan Hai <haishan.bai@...il.com> Subject: [PATCH 1/1] sched/rt: code cleanup, remove a redundant function call The second time call to sched_rt_period is redundant, because the value of the rt_runtime was already read and it was protected by the rurt_runtime_lock.
