perf probe: Support event name for --add option
Support event name syntax for --add option. This allows users to specify event name for each new event. The --add syntax is: perf probe --add '[EVENT=]SRC:LINE ARGS' or perf probe --add '[EVENT=]FUNC[+OFFS|%return|:RLN][@SRC] ARGS' e.g. ./perf probe --add myprobe1=schedule Note: currently group name is not supported yet, because it can cause name-space confliction with other tracepoint/ hw-breakpoint events.
