the goal of having more generic markers is still possible and being 
aimed for - for in-kernel utilization like SystemTap, lttng, utrace, 
ftrace and similar. The latest iteration of markers looks rather 
promising in terms of giving us near-zero-cost probe points.

(and last i checked dtrace was not capable of doing something like 
mmiotrace - so it's a different thing.)

so dont worry :)
