My understanding is mostly, but with some objections. And I kinda
don't want to let this die in a bikeshed and then not getting rid of
follow_pfn as a result. There's enough people who acked this, and the
full removal got some nack from Mauro iirc.

Hmm, ok I must have missed that.  I defintively prefer your series over
doing nothing, but killing the dead horse ASAP would be even better.

I have a bunch of slow-burner things I need to fix in this area of
driver mmaps vs get_user_/follow_ conflicts anyway, I'll add a note to
put the horse out of it's misery in due time. We have a few problems
still where things might get pinned or used where it really shouldn't
be.

Can I count that as an ack on the series? You've touched this quite a
bit recently.

Thanks, Daniel
