    Fair enough.

    I would not mind, for example, leaving the uptodate bit, but removing it
    from the radix tree or something like that (ie turning it into an
    anonymous page for a page-cache page, just removing it from the
    hash-queues for a buffer_head).

    Of course, that could cause other problems (eg any VM assertions that
    shared mappings only contain non-anon pages).
