latency tracing in mainline or rt

[Jack Daniel]

Hi,

Can some one tell me the difference between Latency tracing that's
here http://people.redhat.com/mingo/latency-tracing-patches/ and the
tracing supported in the RT kernel here
http://www.kernel.org/pub/linux/kernel/projects/rt/ ? What's the
status of the present latency tracing and its documentation. Does
Ftrace override these with its superior tracing? Any help is highly
appreciated.


Regards,
Jack
