 Synopsis of kprobe_events
 -------------------------
-  p[:EVENT] SYMBOL[+offs]|MEMADDR [FETCHARGS]  : Set a probe
-  r[:EVENT] SYMBOL[+0] [FETCHARGS]             : Set a return probe
+  p[:[GRP/]EVENT] SYMBOL[+offs]|MEMADDR [FETCHARGS]    : Set a probe
+  r[:[GRP/]EVENT] SYMBOL[+0] [FETCHARGS]               : Set a return probe
 
+ GRP           : Group name. If omitted, use "kprobes" for it.
  EVENT         : Event name. If omitted, the event name is generated
                  based on SYMBOL+offs or MEMADDR.
  SYMBOL[+offs] : Symbol+offset where the probe is inserted.
