From: Ingo Molnar Date: Thu, 9 Aug 2007 09:16:45 +0000 (+0200) Subject: sched: batch sleeper bonus X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0915c4e89d311948b67cdd4c183a2efbcafcc9f9;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git sched: batch sleeper bonus batch up the sleeper bonus sum a bit more. Anything below sched-granularity is too small to make a practical difference anyway. this optimization reduces the math in high-frequency scheduling scenarios.
