What about just passing done_before as an argument to
iomap_dio_complete? gfs2 would have to switch to __iomap_dio_rw +
iomap_dio_complete instead of iomap_dio_rw for that, and it obviously
won't work for async completions, but you force sync in this case
anyway, right?

Add a done_before argument to iomap_dio_rw that indicates how much of
the request has already been transferred. When the request succeeds, we
report that done_before additional bytes were tranferred. This is
useful for finishing a request asynchronously when part of the request
has already been c
