[v1] selftests/mm: Fix false positives and skip unsupported tests

[PATCH 0/6] selftests/mm: Fix false positives and skip unsupported tests

Posted by Aboorva Devarajan 3 months, 3 weeks ago

This patch series fixes some of the false positives in generic
mm selftests and skips tests that cannot run correctly due to
missing features or system limitations.

Please let us know if you have any feedback.

Thanks,  
Aboorva

Hi Aboorva,

It's (highly!) forgivable as things have changed fairly recently, but the
tippy tip of mm development is now done in the mm-new branch, against which
this series doesn't apply.

I thought this might be the case, as there is a series I implemented there
that changes the split huge page tests (possibly affecting more), hence me
checking!

So you'll need to rebase against mm-new, unfortunately!

Thanks, Lorenzo

Hi Lorenzo,

Thanks for pointing this out.

We'll rebase the patches against mm-new and repost them as v2.
