Hi John,

I think you are asking to squash:
https://lore.kernel.org/lkml/20220105061351.120843-8-irogers@xxxxxxxxxx/
into this change. There are other  similar related changes that may
also be squashed. The changes are trying to introduce a new API and
then add changes to switch over to using it. This is with a view to
making bisection easier, have each change only do 1 thing and so on. I
believe the format of the patches is house style, but it is fine to
squash changes together too. Having sent patches to Arnaldo and having
had them split I'm reluctant to do a v5 with them squashed without him
expressing a preference.

Thanks,
Ian
