From e2cf94e4a04b110b18ca43c9988b2d42d915bc11 Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Tue, 12 May 2015 16:41:51 +0200 Subject: [PATCH] sched/preempt: Remove PREEMPT_ACTIVE unmasking off in_atomic() Now that PREEMPT_ACTIVE implies PREEMPT_DISABLE_OFFSET, ignoring PREEMPT_ACTIVE from in_atomic() check isn't useful anymore.
