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. Signed-off-by: Andy Whitcroft <apw@canonical.com> Cc: stable@kernel.org Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
