Unfortunately there's a few more users of ->writepage in addition to
memory reclaim. The most visible on is page migration, but there's also
a write_one_page helper used by a few filesystems that would either
need to get a writepage-like callback or a bigger rewrite.

I agree that killing of ->writepage would be a worthwhile goal, though.
