Masami Hiramatsu d761b08bff perf probe: Reject second attempt of adding same-name event ... Reject second attempt of adding same-name event. This patch also provides --force option which allows user to add additional probe events on the same-name event. e.g. (the first attempt : success) ./perf probe schedule Added new event: probe:schedule (on schedule+0) (the second attempt : failure) ./perf probe schedule:11 Error: event "schedule" already exists. (Use -f to force duplicates.) Fatal: Can't add new event. (the second attempt with -f : successfully added) ./perf probe -f schedule:11 Added new event: probe:schedule_1 (on schedule+45) Signed-off-by: Masami Hiramatsu <mhiramat@redhat.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Jim Keniston <jkenisto@us.ibm.com> Cc: Ananth N Mavinakayanahalli <ananth@in.ibm.com> Cc: Christoph Hellwig <hch@infradead.org> Cc: Frank Ch.
