2008-05-23Port ftrace to markersMathieu Desnoyers1-28/+143
Porting ftrace to the marker infrastructure. Don't need to chain to the wakeup tracer from the sched tracer, because markers support multiple probes connected.

2008-05-23ftrace: fix comm on function trace outputSteven Rostedt1-2/+5
In cleaning up of the sched_switch code, the function trace recording of task comms was removed. This patch adds back the recording of comms for function trace. The output of ftrace now has the task comm instead of <...>.
