Subject: [PATCH ftrace/for-next V2] tracing/kprobes: Add selftest scripts testing kprobe-tracer as startup test
Date: Wed, 08 Oct 2014 04:03:07 +0000 [thread overview]
Message-ID: <20141008040307.13415.45145.stgit@kbuild-f20.novalocal> (raw)
Add two selftest scripts which tests kprobe-tracer as the startup
selftest does.
These test cases are testing that the kprobe_event can accept a
kprobe event with $stack related arguments and a kretprobe event
with $retval argument.
