From 130816ce4d5f69167324f7272e70aa3d641677c6 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Wed, 11 Dec 2013 12:21:17 +0100 Subject: [PATCH] sched, thermal: Clean up preempt_enable_no_resched() abuse The only valid use of preempt_enable_no_resched() is if the very next line is schedule() or if we know preemption cannot actually be enabled by that statement due to known more preempt_count 'refs'.
