From 0915c4e89d311948b67cdd4c183a2efbcafcc9f9 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Thu, 9 Aug 2007 11:16:45 +0200 Subject: [PATCH] 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.
