I'd like to know whether it is possible for a cache target for which
there are dirty blocks to continue writing back dirty data after it
has been suspended. Can this happen? I checked the code and
cache_postsuspend() suggests that after the target is suspended no
write back I/O will be initiated (I also did a quick test that
confirms this), however I'd appreciate an answer from the maintainers
as I might have misunderstood.
