+                       [FTRACE] Add kprobe events and enable at boot time.
+                       The probe-list is a semicolon delimited list of probe
+                       definitions. Each definition is same as kprobe_events
+                       interface, but the parameters are comma delimited.
+                       For example, to add a kprobe event on vfs_read with
+                       arg1 and arg2, add to the command line;
+
+                             kprobe_event=p,vfs_read,$arg1,$arg2
