Subject: [patch] ftrace, v15
the current/latest ftrace tree can be pulled from:
git://git.kernel.org/pub/scm/linux/kernel/git/mingo/linux-2.6-sched-devel.git
the full diffs are too large to be included here, but the shortlog and
the diffstat is below. Not much changed in the fundamentals since the
last lkml posting - but many small details were refined.
