From de5bdff7a72acc281219be2b8edeeca1fd81c542 Mon Sep 17 00:00:00 2001 From: Hiroshi Shimamoto Date: Thu, 16 Feb 2012 14:52:21 +0900 Subject: sched: Make initial SCHED_RR timeslace DEF_TIMESLICE Current the initial SCHED_RR timeslice of init_task is HZ, which means 1s, and is not same as the default SCHED_RR timeslice DEF_TIMESLICE. Change that initial timeslice to the DEF_TIMESLICE.
