Hi, Mathieu,

I strongly reject for removing tracepoint_mutex and marker_mutex.

As an independent subsystem, we should use our own locks. Do not use others.
otherwise coupling will be increased in linux kernel.
I condemn unnecessary coupling.

Our tracepoint & marker had tied to modules(for traveling all tracepoints
or markers). The best thing is that we do not increase the coupling.

[PATCH 2/2] tracepoint: introduce *_noupdate APIs.
is helpful for auto-active-tracepoint-mechanism.

		Thanx, Lai.
