 Overview
 --------
-This tracer is similar to the events tracer which is based on Tracepoint
-infrastructure. Instead of Tracepoint, this tracer is based on kprobes(kprobe
-and kretprobe). It probes anywhere where kprobes can probe(this means, all
-functions body except for __kprobes functions).
+These events are similar to tracepoint based events. Instead of Tracepoint,
+this is based on kprobes (kprobe and kretprobe). So it can probe wherever
+kprobes can probe (this means, all functions body except for __kprobes
+functions). Unlike the Tracepoint based event, this can be added and removed
+dynamically, on the fly.
 
-Unlike the function tracer, this tracer can probe instructions inside of
-kernel functions. It allows you to check which instruction has been executed.
+To enable this feature, build your kernel with CONFIG_KPROBE_TRACING=y.
 
-Unlike the Tracepoint based events tracer, this tracer can add and remove
-probe points on the fly.

-Similar to the events tracer, this tracer doesn't need to be activated via
-current_tracer, instead of that, just set probe points via
-/sys/kernel/debug/tracing/kprobe_events. And you can set filters on each
-probe events via /sys/kernel/debug/tracing/events/kprobes/<EVENT>/filter.

  Per-probe event filtering feature allows you to set different filter on each
