Hello,
I am working on rebasing the labeled-nfs patches on a newer kernel
version and readding the label translation code in. I don't believe that
I have touched anything related to the rpc client creation code. When I
try to mount my nfsv4 share I am getting this error
svc: 127.0.0.1, port=717: unknown version (4 for prog 100003, nfsd)
This gives me the indication that whatever is throwing off that message
doesn't recognize nfsv4 as a valid version for NFS.
I've pasted the output of a mount attempt with rpcdebug -m
{rpc,nfs,nfsd} all set to all.
