From c9c024b3f3e07d087974db4c0dc46217fff3a6c0 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Mon, 5 Dec 2011 21:20:23 +0100 Subject: alarmtimers: Fix time comparison The expiry function compares the timer against current time and does not expire the timer when the expiry time is >= now. That's wrong. If the timer is set for now, then it must expire. Make the condition expiry > now for breaking out the loop.
