From b5d7682533941edb121f7495bdb2a17abac03ff3 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 11 Jun 2014 23:59:13 +0000 Subject: delayacct: Use ktime_get_ts() do_posix_clock_monotonic_gettime() is a leftover from the initial posix timer implementation which maps to ktime_get_ts(). Remove the silly wrapper while at it.
