Subject: [PATCH v3 04/12] sched/fair: Add __always_inline compiler attribute to __accumulate_sum()
Date: Wed, 4 May 2016 04:02:45 +0800 [thread overview]
Message-ID: <1462305773-7832-5-git-send-email-yuyang.du@intel.com> (raw)
In-Reply-To: <1462305773-7832-1-git-send-email-yuyang.du@intel.com>
Everybody has it. If code-size is not the problem, __accumulate_sum()
should have it too.
