how is this to work with power management domains?

Could you explain it in a bit detail? Why is PM domain involved?

Suppose PM domain is involved, its domain runtime_resume callback
is still run in the context with PF_MEMALLOC_NOIO flag set if the
affected 'device' is passed to the callback.

And I may be dense, but disks are added in slave_configure().
This seems to be a race to me.

Sorry, could you describe what is the race?

Suppose drivers set correct parent device to the disk device(gendisk),
then add the disk into device model via register_disk(), the solution
should be fine.

Thanks,
