Commit-ID: 1bbfa6f25673019dc0acc9308b667c96f6cda8bf Gitweb: http://git.kernel.org/tip/1bbfa6f25673019dc0acc9308b667c96f6cda8bf Author: Mike Frysinger <vapier@xxxxxxxxxx> AuthorDate: Wed, 9 Dec 2009 20:07:03 -0500 Committer: Ingo Molnar <mingo@xxxxxxx> CommitDate: Thu, 10 Dec 2009 08:30:27 +0100 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.
