It's just good manners :) Especially when you're just moving an
existing definition around.

In some cases we're forced to use 'int' instead of the specific
enum because... Reasons. I forget :) But I dont think this is one of
those cases.
Considering that this patch is pure code motion (plus dealing with
the fallout of such code motion), it would not be very appropriate to
alter the function signature during the process. And anyway, none of
this really matters: we're gonna drop both the enum and the functions
in the next patch.

I don't think the difference is intentional: just code written by
different developers and/or at different points in time. And again,
not something that it would be appropriate to change in this patch.

Agreed.

It's usually frowned upon, though it's prefectly normal that
something will slip in, especially in the context of a fairly large
series such as this one.
Please split off that change to its own, trivial patch. With that
addressed,
