Yeah, I think the requirement is just "it has to be against some commit
that is on the mainline of the upstream kernel", it doesn't inherently
have to be an rc or a full point release. The assumption we're making
here is that ABI is stable once a change hits Linus' git tree, and
not stable before that.

The other requirement is "don't go backwards", ie don't sync to a
commit that pre-dates whatever the last commit we synced to is.

The last sync we did was to ceaa837f96ad ("Linux 6.2-rc8").
