tracing/ksym_tracer: fix write operation of ksym_trace_filter
This patch fix 2 bugs: - fix the return value of ksym_trace_filter_write() when we want to clear symbol in ksym_trace_filter file for example: # echo global_trace:rw- > /debug/tracing/ksym_trace_filter # echo global_trace:--- > /debug/tracing/ksym_trace_filter -bash: echo: write error: Invalid argument # cat /debug/tracing/ksym_trace_filter # We want to clear 'global_trace' in ksym_trace_filter, it complain with "Invalid argument", but the operation is successful - the "r--" access types is not allowed, but ksym_trace_filter file think it OK for example: # echo ksym_tracer_mutex:r-- > ksym_trace_filter -bash: echo: write error: Resource temporarily unavailable # dmesg ksym_tracer request failed. Try again later!! The error occur at register_kernel_hw_breakpoint(), but It's should at access types parser Signed-off-by: Xiao Guangrong <xiaoguangrong@cn.fujitsu.com> LKML-Reference: <4A66863D.5090802@cn.fujitsu.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
