BLKTRACE is a special-purpose tracing facility limited to one subsystem
and written and maintained by the /same/ person (Jens) who maintains
that subsystem. He maintains the subsystem, the tracer and the userspace
tool that extracts the tracer data.
LTT on the other hand is a static tracer that affects _all_ subsystems.
That is a very different situation from a maintainance overhead POV, and
i believe you must know that.
your suggestion that this controversy has prevented consolidation in
this area is baseless and misleading, please correct or retract it.
