Subject: [PATCH V2 19/19] tick-sched: rearrange code in tick_do_update_jiffies64()
Date: Mon, 21 Apr 2014 15:25:15 +0530 [thread overview]
Message-ID: <c0c4a829b4f938d002adb79f2661474be913acee.1398072824.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1398072824.git.viresh.kumar@linaro.org>
In-Reply-To: <cover.1398072824.git.viresh.kumar@linaro.org>
The last two lines of tick_do_update_jiffies64() are only executed when
'delta.tv64 >= tick_period.tv64'. Move them to the 'if' block to make it more
clear.
