From 198fa445d5c4c1a1c6c1d39f962559f8d008e79d Mon Sep 17 00:00:00 2001 From: Andrei Vagin Date: Tue, 12 Nov 2019 01:26:59 +0000 Subject: posix-timers: Use clock_get_ktime() in common_timer_get() Now, when the clock_get_ktime() callback exists, the suboptimal timespec64-based conversion can be removed from common_timer_get().
