Subject: [PATCH 3/7] s390: monotonic_clock interface.
Date: Wed, 18 Jan 2006 17:52:54 +0100 [thread overview]
Message-ID: <20060118165254.GC29266@osiris.boeblingen.de.ibm.com> (raw)
From: Jan Glauber <jan.glauber@de.ibm.com>
Add monotonic_clock interface, used by the hangcheck-timer.
On s390 this is the same as sched_clock().
