Date: Mon, 16 May 2016 02:59:31 +0800 From: Yuyang Du <yuyang.du@...el.com> To: peterz@...radead.org, mingo@...nel.org, linux-kernel@...r.kernel.org Cc: bsegall@...gle.com, pjt@...gle.com, morten.rasmussen@....com, vincent.guittot@...aro.org, dietmar.eggemann@....com, juri.lelli@....com, Yuyang Du <yuyang.du@...el.com> Subject: [RFC PATCH 6/9] sched/fair: Add __always_inline compiler attribute to __accumulate_sum() __accumulate_sum()'s caller and sibling functions are all inlined. And it will be called almost every time in its caller. It does not make sense if only it is not inlined.
