Although it's just me, I'd prefer sioq_init(), sioq_exit(),
sioq_run(), etc. to go in hand with what most drivers use as naming
(i.e. <modulename> "_" <function>).

Beat me: what does SIO stand for?

No __exit tag?

Care to make that: const struct mknod_args *m = &args->mknod;?
(Same for other places)

This name puzzled me at first. iso - paque - "same (o)paque"?
Try is_opaque_args.
