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).
