-          This tracer probes everywhere where kprobes can probe it, and
-          records various registers and memories specified by user.
-          This also allows you to trace kprobe probe points as a dynamic
-          defined events. It provides per-probe event filtering interface.
+          This allows the user to add tracing events (similar to tracepoints) on the fly
+          via the ftrace interface. See Documentation/trace/kprobetrace.txt
+          for more details.
+
+          Those events can be inserted wherever kprobes can probe, and record
+          various register and memory values.
+
+          This option is also required by perf-probe subcommand of perf tools. If
+          you want to use perf tools, this option is strongly recommended.
