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 Signed-off-by: Xiao Guangrong <xiaoguangrong@cn.fujitsu.com> LKML-Reference: <4A67E092.3080202@cn.fujitsu.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
