From 391e43da797a96aeb65410281891f6d0b0e9611c Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Tue, 15 Nov 2011 17:14:39 +0100 Subject: [PATCH] sched: Move all scheduler bits into kernel/sched/ There's too many sched*.[ch] files in kernel/, give them their own directory. (No code changed, other than Makefile glue added.)
