Regular file support in Linux blkback?

[Demi Marie Obenour <demi@xxxxxxxxxxxxxxxxxxxxxx>]

What would be involved in supporting regular files in Linux blkback?  Is
it just a matter of using the call_{read,write}_iter functions for read
and write, and punting the work that cannot be done asynchronously to a
thread pool?  Or is it more complex than that?
