This doesn't have to do with the deferred swap. Without your
quick patch ramfs would be nothing but a memory leak.
Imagine deleting 30MB of files from ramfs and keeping the
dirty bit. If we would reuse that memory later for caching some
files from CDROM or disk, they would still have the dirty bit
set and shrink_mmap() would always skip them ...
