Message-Id: <1260407223-10900-1-git-send-email-vapier@gentoo.org> Date: Wed, 9 Dec 2009 20:07:03 -0500 From: Mike Frysinger <vapier@...too.org> To: Ingo Molnar <mingo@...e.hu>, Peter Zijlstra <peterz@...radead.org> Cc: linux-kernel@...r.kernel.org Subject: [PATCH] sched: mark sched_clock() as notrace The core ftrace code (trace_clock_local) calls sched_clock() directly, so we don't want to recurisvely trigger the ftrace code. Rather than update every sched_clock() definition, tag the prototype for everyone as notrace.
