Subject: [PATCH v6 18/21] selftests: ftrace: Add a testcase for $argN with kprobe_event
Date: Sat, 17 Mar 2018 21:50:54 +0900 [thread overview]
Message-ID: <152129105459.31874.15978479654038019110.stgit@devbox> (raw)
Message-ID: <20180317125054.6uJgjLt55cw3-9_B1xZppiaQUT-pigLlXUS4_VQIkRU@z> (raw)
In-Reply-To: <152129024033.31874.15800253385376959274.stgit@devbox>
Add a testcase for $argN with kprobe event.
This tests whether the traced data is correct or not.
If the kernel doesn't support $argN (depends on arch),
it skips the test as UNSUPPORTED.
