From 8c6a98b22b750c9eb52653ba643faa17db8d3881 Mon Sep 17 00:00:00 2001 From: Andy Whitcroft Date: Mon, 24 Jan 2011 09:31:38 -0800 Subject: Input: sysrq - ensure sysrq_enabled and __sysrq_enabled are consistent Currently sysrq_enabled and __sysrq_enabled are initialised separately and inconsistently, leading to sysrq being actually enabled by reported as not enabled in sysfs. The first change to the sysfs configurable synchronises these two: static int __read_mostly sysrq_enabled = 1; static int __sysrq_enabled; Add a common define to carry the default for these preventing them becoming out of sync again. Default this to 1 to mirror previous behaviour.
