From 77f4fa089c724adc3a87c10eb031bca91b144ac0 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 11 Jun 2014 23:59:19 +0000 Subject: [PATCH] tomoyo: Use sensible time interface There is no point in calling gettimeofday if only the seconds part of the timespec is used. Use get_seconds() instead. It's not only the proper interface it's also faster.
