The issue is 916d2d844afd "nfsd: clean up supported attribute handling" dcd208697707 "nfsd: fix supported attributes for acl & labels" which replaced 3 numbered constants by an array, and went in between 4.8 and 4.10. But for the purposes of older stable branches, best is probably just to use the old constants.
