If I understand this correctly, during the rework (by Eric I assume) some of
your fixes got invalidated. Yet the current code and binaries produced are
not worse off then before the patches.

Thus from stable POV, we're safe, since nothing has regressed per se. We will
apply the extra patches for the next release.

Thanks

P.S. How did you submit the patches - I cannot see them neither on mesa-dev
mailing list nor gitlab MR.
