So maybe it is still useful for a non-rt kernel. But what serious
audio user would use a non-rt kernel?
I think more will use the mainline kernel as it gets better (keyboard
players are perfectly fine with 5ms latency which mainline can certainly
deliver). And the latency tracer has overhead (if you oprofile it you
will see mcount() eats 1-2% of your CPU), and is complicated for users
who aren't linux experts to use.
We know the -rt kernel is OK for audio, but it would be nice to be able
to tell users "is this random kernel that I am running likely to be OK
for audio"
