Subject: [03/45] alarmtimers: Fix time comparison
Date: Fri, 16 Dec 2011 11:40:10 -0800 [thread overview]
Message-ID: <20111216194207.204944899@clark.kroah.org> (raw)
In-Reply-To: <20111216194603.GA15028@kroah.com>
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Thomas Gleixner <tglx@linutronix.de>
commit c9c024b3f3e07d087974db4c0dc46217fff3a6c0 upstream.
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.
