tracing/ksym_tracer: support quick clear for ksym_trace_filter -- v2
It's rather boring to clear symbol one by one in ksym_trace_filter
file, so, this patch will let ksym_trace_filter file support quickly
clear all break points. We can write "0" to this file and it will clear
all symbols
for example:
# cat ksym_trace_filter
ksym_filter_head:rw-
global_trace:rw-
# echo 0 > ksym_trace_filter
# cat ksym_trace_filter
#
Changelog v1->v2:
Add other ways to clear all breakpoints by writing NULL or "*:---"
to ksym_trace_filter file base on K.Prasad's suggestion
