Good morning!
How feasible would be a realtime NFSv4, which can guarantee NFSv4
operations in a constant time manner suitable for realtime
applications (similar to XFS realtime support)?
Yes, I know NFSv4 uses TCP, which is a bit allergic to realtime, but
aside from that (there is always RTP), can the NFSv4 protocol and
Linux implementation be modified for constant time?

The XFS realtime subvoume is grossly misnamed, it does not guarantee
anything at all. It just uses a separate, somewhat more predicatable
allocator.
