crypto/block-qcow.c also refers to the changed the types, but does not
care about its parameters, so it looks like you got everything.

Moving 'opaque' like this should not be done.
If you want the compiler to check the fixes, it should be done in
just two stages. First move errp & move opaque to start, compile
it & verify. Then put opaque back to where it was, and compile
again. The resulting commit thus only has the errp move, not the
unrelated & uneccessary opaque move.

The idea is to let everyone's compiler verifies this patch, and also to avoid
possible bugs introduced in backporting/rebasing/merging - for example if a
patch in another tree addes one more implementation that uses the old order, we
can notice.
If you don't like this, we can be careful and don't move opaque; or after a
short while, move opaque back in a separate commit (since Markus already sent a
pull request).

I'm prepared to NAK my pull request if we think we need more time to
discuss the patches.

That is true in general, but in reality this particular function is not
widely used and so chance of there being another out of tree impl is
essentially zero.

It isn't a big deal either way. I can just send a follow up patch if needed
