From c9cb2e3d7c9178ab75d0942f96abb3abe0369906 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Fri, 16 Feb 2007 01:27:49 -0800 Subject: [PATCH] hrtimers: namespace and enum cleanup - hrtimers did not use the hrtimer_restart enum and relied on the implict int representation. Fix the prototypes and the functions using the enums. - Use seperate name spaces for the enumerations - Convert hrtimer_restart macro to inline function - Add comments No functional changes.
