Subject: [PATCH] sched/fair: Set se->vruntime directly in place_entity()
Date: Thu,  8 Nov 2012 13:33:46 +0530
Message-ID: <ae59db1945518d6f6250920d46eb1f1a9cc0024e.1352361704.git.viresh.kumar@linaro.org> (raw)

We are first storing the new vruntime in a variable and then storing it in
se->vruntime. Simply update se->vruntime directly.
