The page providers which try to reuse the same pages will
need to hold onto the ref, even if page gets released from
the pool - as in releasing the page from the pp just transfers
the "ownership" reference from pp to the provider, and provider
will wait for other references to be gone before feeding this
page back into the pool.

Likely needs a Cc: Christoph Hellwig <hch@xxxxxx>, given previous
feedback to this patch?
I wouldn't bother, I don't believe it's done in good faith.
But that's going to run into the same feedback again. You don't want
to do this without the ops again?
Well, the guy sprinkles nacks as confetti, it's getting hard
to take it seriously. It's a net change, I'll leave it to the
net maintainers to judge.
