These [k,u]probe are associated with the file decriptor created by perf_event_open(), thus are easy to clean when the file descriptor is destroyed. kprobe_func and uprobe_path are added to union config1 for pointers to function name for kprobe or binary path for uprobe. kprobe_addr and probe_offset are added to union config2 for kernel address (when kprobe_func is NULL), or [k,u]probe offset.
