From 5e05ad7d4e3b11f935998882b5d9c3b257137f1b Mon Sep 17 00:00:00 2001 From: Davide Libenzi Date: Mon, 4 Feb 2008 22:27:25 -0800 Subject: timerfd: introduce a new hrtimer_forward_now() function I think that advancing the timer against the timer's current "now" can be a pretty common usage, so, w/out exposing hrtimer's internals, we add a new hrtimer_forward_now() function.
