From a0a522ce3d6d8c907e45d4f2730ee8573484cc88 Mon Sep 17 00:00:00 2001 From: Henrik Austad Date: Fri, 13 Feb 2009 20:35:45 +0100 Subject: sched: idle_at_tick is only used when CONFIG_SMP is set Impact: struct rq size optimization The idle_at_tick in struct rq is only used in SMP settings and it does not make sense to have this in the rq in an UP setup.
