From 06027bdd278a32a84b273e41db68a5db8ffd2bb6 Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Tue, 14 Feb 2006 13:53:15 -0800 Subject: [PATCH] hrtimer: round up relative start time on low-res arches CONFIG_TIME_LOW_RES is a temporary way for architectures to signal that they simply return xtime in do_gettimeoffset(). In this corner-case we want to round up by resolution when starting a relative timer, to avoid short timeouts. This will go away with the GTOD framework.
