Indeed. It may be interesting to point out the systemtap script interface
to the markers - for those who don't want to write their instrumentation
in C. This one just traces the first argument. (It's already working,
which makes sense since we prototyped markers with/before Mathieu.)

probe kernel.mark("name") { println ($arg1) }

We look forward to the inclusion of markers in linux, and their gradual
utilization throughout the code base.
