Ah, I see what you're talking about. In theory we make rw_swap_page use
the page cache operations of the filesystem (or block device) by simply
relabelling the page from its swap cache entry. Actually, if we use the
page cache for block device access, doesn't that mean that we can get rid
of the swapper_inode completely? This seems like an obvious way of doing
things, and unless people point out something that I'm missing entirely
here... It'll mean that brw_page goes away and is replaced by the use of
i_ops->readpage. That's seems good =)
