From 5710f15b52664ae0bfa60a66d75464769d297b2b Mon Sep 17 00:00:00 2001 From: Yong Zhang Date: Sat, 6 Aug 2011 08:10:04 +0800 Subject: [PATCH] sched/cpupri: Remove cpupri->pri_active Since [sched/cpupri: Remove the vec->lock], member pri_active of struct cpupri is not needed any more, just remove it. Also clean stuff related to it.
