v6.10 has been released already, and it will be a couple months before
the v6.11 release.

It looks like the regression is 407d1a51921e, which appeared in v6.6,
almost a year ago, so it's fairly old.

What target are you thinking about for the V1 patch?  I guess if we
add it as a v6.11 post-merge window fix, it might get backported to
stable kernels before v6.11?  But if the plan is to merge the V1 patch
and then polish it again before v6.11 releases, I'm not sure it's
worth the churn.
