From 0b8473570ce1af3e80da05b59f9321f30253de4d Mon Sep 17 00:00:00 2001 From: Cheng Chao Date: Wed, 14 Sep 2016 10:18:56 +0800 Subject: [PATCH] sched/core: Remove unnecessary initialization in sched_init() init_idle() is called immediately after: current->sched_class = &fair_sched_class; init_idle() sets: current->sched_class = &idle_sched_class; First assignment is superfluous.
