Subject: [PATCH v6 03/21] selftests: ftrace: Add a testcase for string type
 with kprobe_event
In-Reply-To: <152129024033.31874.15800253385376959274.stgit@devbox>
References: <152129024033.31874.15800253385376959274.stgit@devbox>
Message-ID: <152129038381.31874.9201387794548737554.stgit@devbox>

Add a testcase for string type with kprobe event.
This tests good/bad syntax combinations and also
the traced data is correct in several way.
