perf probe: List probes with line number and file name
Improve --list to show current exist probes with line number and file name. This enables user easily to check which line is already probed. for example: ./perf probe --list probe:vfs_read (on vfs_read:8@linux-2.6-tip/fs/read_write.c) Signed-off-by: Masami Hiramatsu <mhiramat@redhat.com> Cc: systemtap <systemtap@sources.redhat.com> Cc: DLE <dle-develop@lists.sourceforge.net> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Mike Galbraith <efault@gmx.de> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> LKML-Reference: <20100316220619.32050.48702.stgit@localhost6.localdomain6> Signed-off-by: Ingo Molnar <mingo@elte.hu>
