Subject: [PATCH 0/3] [PATCH] more sched_clock updates
Date: Wed, 09 Jul 2008 00:15:30 -0400	[thread overview]
Message-ID: <20080709041530.668120406@goodmis.org> (raw)

ftrace is still seeing jumps in the sched_clock.c code that is not seen in
using sched_clock() function itself. The following patches fix some of
the issues that I've seen. There is still a slight drift but all my attempts
to remove it completely have failed. Patch 3 does the best sofar at
keeping the jumps to a minimum.
