From 5b680fd61388abb9059fbc8e7a2f60f602bfce15 Mon Sep 17 00:00:00 2001 From: Shan Hai Date: Tue, 29 Nov 2011 11:03:56 +0800 Subject: [PATCH] sched/rt: Code cleanup, remove a redundant function call The second call to sched_rt_period() is redundant, because the value of the rt_runtime was already read and it was protected by the ->rt_runtime_lock.
