It's nice to have this feature added and the other patches fix issues in
ksym tracer. Can you have this patch add the capability to clear all
breakpoints in one-shot through wild-cards?

Ingo wanted something like "echo "*:---" > ksym_trace_filter". The patch
I sent here: http://lkml.org/lkml/2009/6/20/73 implements the same. You
may want to implement something on those lines.

Thanks,
K.Prasad
