Message-ID: <20080714142226.GA11412@elte.hu>
Date: Mon, 14 Jul 2008 16:22:26 +0200
From: Ingo Molnar <mingo@...e.hu>
To: Linus Torvalds <torvalds@...ux-foundation.org>

Subject: [git pull] ftrace for v2.6.27
Linus,
Please pull the ftrace git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git tracing/for-linus
[ NOTE: please pull this only after the x86/for-linus and
sched/for-linus pulls, as it's a manual merge ontop of those branches. ]
This tree adds the ftrace framework and a couple of tracing plugins:
ftrace, latency tracer, x86/mmiotrace, irqs-off tracer, sysprof,
scheduler tracer.
Thanks,
Ingo
