From 26a148eb9c790149750f7e77da0d96029443d400 Mon Sep 17 00:00:00 2001 From: Richard Kennedy Date: Fri, 15 Jul 2011 11:41:31 +0100 Subject: [PATCH] sched: Reorder root_domain to remove 64 bit alignment padding Reorder root_domain to remove 8 bytes of alignment padding on 64 bit builds, this shrinks the size from 1736 to 1728 bytes, therefore using one fewer cachelines.
