From 170e22e8d727d6421e74b16c7f6747499c068fc3 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Wed, 9 Apr 2014 10:37:23 +0200 Subject: [PATCH 211/365] block: mq: use cpu_light() there is a might sleep splat because get_cpu() disables preemption and later we grab a lock. As a workaround for this we use get_cpu_light().
