Subject[GIT PULL] Kselftest update for 4.14-rc1
Date
Hi Linus,

Please pull the following Kselftest update for 4.14-rc1.

This update consists of:

-- TAP13 framework API and converting tests to TAP13 continues. A few
more tests are converted and kselftest common RUN_TESTS in lib.mk
is enhanced to print TAP13 to cover test shell scripts that won't
be able to use kselftest API.

-- Several fixes to existing tests to not fail in unsupported cases.
This has been an ongoing work based on the feedback from stable
release kselftest users.

-- A new watchdog test and much needed cleanups to the existing tests
from Eugeniu Rosca.

-- Changes to kselftest common lib.mk framework to make RUN_TESTS a
function to be called from individual test make files to run stress
and destructive sub-tests.

Diff for the update attached.

thanks,
-- Shuah
