Makes sense, but why change the arguments?

Not sure I understand. Do you mean the change from untyped args and res
to nfs4_sequence_args and nfs4_sequence_res? That would be to enable
proper type checking.
That part of the macro was always a dirty hack which relied on the
sequence related arguments always having the same names, and which only
served to avoid having to type those 8 characters per argument...

It would be nice to document that improvement in the patch description.
