perf probe: Show filename which contains target function
Show filename which contains a target function with the function name on "--lines" mode, because perf-probe just shows the first function even if there are many same-name functions.
Originally adopted by Franck Bui-Huu's patch which shows file name instead of function name. I've just modified it to show both of function name and file name, because of completeness of output.
E.g.) $ perf probe -L t_show <t_show@/home/mhiramat/ksrc/linux-2.6-tip/kernel/trace/ftrace.c:0> 0 static int t_show(struct seq_file *m, void *v) 1 { 2 struct ftrace_iterator *iter = m->private; ...
$ perf probe -L t_show@trace/trace.c <t_show@/home/mhiramat/ksrc/linux-2.6-tip/kernel/trace/trace.c:0> 0 static int t_show(struct seq_file *m, void *v) 1 { struct tracer *t = v; ...
