This step mechanism may be useful to return an information about the
error without being able to write to TH_LOG_STREAM.

Set _metadata->no_print to true to print this counter.

This patch is intended to the kselftest tree:
https://lkml.kernel.org/r/20170806232337.4191-1-mic at digikod.net

Changes since v6:
* add the step counter in assert/expect macros and use _metadata to
  enable the counter (suggested by Kees Cook)

is there a dependency on this in patches 2+ ?
if not, I would send this patch to selftests right away.

The Landlock tests [patch 9/10] rely on it for now.

I sent it three weeks ago:
https://lkml.kernel.org/r/20170806232337.4191-1-mic at digikod.net

Anyway, until this patch is merged in the kselftest tree and then
available to net-next, I'll have to keep it here.

Shuah,
could you please pick up this patch into your tree?

Thanks. Applied to linux-kselftest next for 4.14-rc1.
