From dedad90edc15c1c487350d015660dc18336380a1 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Tue, 9 Feb 2016 18:17:18 +0100 Subject: [PATCH 156/352] kernel: softirq: unlock with irqs on We unlock the lock while the interrupts are off. This isn't a problem now but will get because the migrate_disable() + enable are not symmetrical in regard to the status of interrupts.
