I applied the patch below on top of current mainline and passed itResult is that every build with NFS configured but not NSFv3 is
now broken.
Fortunately a v2-only server would be pretty unusual these days.
I don't know, maybe this?

nfsd4: fix v3-less build
Includes of pnfs.h in export.c and fcntl.c also bring in xdr4.h, which
won't build without CONFIG_NFSD_V3, breaking non-V3 builds. Ifdef-out
most of pnfs.h in that case.
