Here's my attempt at making the top (ie the part of ceph that interacts with the page cache) folio-aware. Mostly this is just phasing out use of struct page in favour of struct folio and using the new APIs. The fscrypt interaction still needs a bit of work, but it should be a little easier now. There's still some weirdness in how ceph interacts with the page cache; for example it holds folios locked while doing writeback instead of dropping the folio lock after setting the writeback flag. I'm not sure why it does that, but I don't want to try fixing that as part of this series. I don't have a ceph setup, so these patches are only compile tested. I really want to be rid of some compat code, and cecph is sometimes the last user (or really close to being the last user).
