Hi Linus,
Please pull the following update for 4.13-rc1
This update consists of:
-- TAP13 framework and changes to some tests to convert to TAP13.
Converting kselftest output to standard format will help identify
run to run differences and pin point failures easily. TAP13 format
has been in use for several years and the output is human friendly.
Please find the specification:
https://testanything.org/tap-version-13-specification.html
Credit goes to Tim Bird for recommending TAP13 as a suitable format,
and to Grag KH for kick starting the work with help from Paul Elder
and Alice Ferrazzi
The first phase of the TAP13 conversion is included in this update.
Future updates will include updates to rest of the tests.
-- Masami Hiramatsu fixed ftrace to run on 4.9 stable kernels.
-- Kselftest documnetation has been converted to ReST format. Document
now has a new home under Documentation/dev-tools.
-- kselftest_harness.h is now available for general use as a result of
Mickaël Salaün's work.
-- Several fixes to skip and/or fail tests gracefully on older releases.
Diff for the update attached.
thanks,
-- Shuah
