perf probe: Add --list option for listing current probe events Add --list option for listing currently defined probe events in the kernel. This shows events in below format; [group:event] <perf-probe probe-definition> for example: [probe:schedule_0] schedule+30 cpu Note that source file/line information is not supported yet. So even if you added a probe by line, it will be shown in <symbol+offset>.

perf probe: Simplify event naming Simplify event naming as <symbol>_<seqnum>. Each event name is globally unique (group name is not checked). So, if there is schedule_0, next probe event on schedule() will be schedule_1.
