Subject: net: convert sunrpc from pagevec to folio_batch
Date: Wed, 21 Jun 2023 17:45:53 +0100
Remove the last usage of pagevecs. There is a slight change here; we now
free the folio_batch as soon as it fills up instead of freeing the
folio_batch when we try to add a page to a full batch. This should have
no effect in practice.
