I think the best fix is to have the ramdisk using the same aops of ramfs
and replace "Secure" with "Uptodate". We need to trap the security issue
at the higher layer and also this will avoid us having to map useless
bh, so it should be an improvement, only the filesystem will end
triggering the ->make_request callback of the ramdisk. Then if the fs
does I/O on stuff out of the physical address space we'll just clear it
out.
