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

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
