Date: Fri, 17 Oct 2014 19:06:22 +0200 From: Ulrich Obergfell <uobergfe@...hat.com> To: linux-kernel@...r.kernel.org Cc: dzickus@...hat.com, uobergfe@...hat.com Subject: [PATCH v2 3/9] watchdog: move definition of 'watchdog_proc_mutex' outside of proc_dowatchdog() This series removes the proc_dowatchdog() function. Since multiple new functions need the 'watchdog_proc_mutex' to serialize access to the watchdog parameters in /proc/sys/kernel, move the mutex outside of any function.
