As a point merely of style, you don't need the ( .. ) around the
then-clause if you don't want it (but in that case the pr command must
be followed by a semicolon).

New OCaml actually has unsigned types, but we probably don't want to
depend on that version yet so this is OK as it is.

This patch looks fine, can't see any problems, so ACK.

There are a handful of places in tests and examples where we assign
nbd_aio_get_direction to an int variable, usually called ’dir’.  Maybe
we should replace those with unsigned variables?
