From 10b777246c6953100099af1870d35c8b24d49b12 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Fri, 9 Nov 2007 22:39:37 +0100 Subject: [PATCH] sched: fix vslice vslice was missing a factor NICE_0_LOAD, as weight is in weight*NICE_0_LOAD units. the effect of this bug was larger initial slices and thus latency-noisier forks.
