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
