From 174bd1994ec67a6e6191c4ed8e5dac17fa221b84 Mon Sep 17 00:00:00 2001 From: Stanislaw Gruszka Date: Tue, 25 May 2010 23:49:12 +0200 Subject: [PATCH] hrtimer: Avoid double seqlock hrtimer_get_softirq_time() has it's own xtime lock protection, so it's safe to use plain __current_kernel_time() and avoid the double seqlock loop.
