From 1d7e974cbf2fce2683f34ff33c173fd7ef5478c7 Mon Sep 17 00:00:00 2001 From: Wanpeng Li Date: Tue, 14 Oct 2014 10:22:39 +0800 Subject: [PATCH] sched/deadline: Don't check SD_BALANCE_FORK There is no need to do balance during fork since SCHED_DEADLINE tasks can't fork. This patch avoid the SD_BALANCE_FORK check.
