Subject: [PATCH] sched: Use time_after()
Date: Thu, 22 May 2014 19:45:23 +0200 [thread overview]
Message-ID: <1400780723-24626-1-git-send-email-manuel.schoelling@gmx.de> (raw)
To be future-proof and for better readability the time comparisons are modified
to use time_after() instead of plain, error-prone math.
Signed-off-by: Manuel Schölling <manuel.schoelling@gmx.de>
