Can you please be more specific.
I'm not sure what you're referring to...

GETDEVICEINFO doesn't use the current filehandle.
GETDEVICELIST must have a valid filehandle.

Hmm, that's wrong.  GETDEVICEINFO needs no file handle
[nfsv4 mailing list Cc'ed]
I think that NFS4ERR_FHEXPIRED should allowed for all ops that
are allowed to return NFS4ERR_NOFILEHANDLE.  This seems like
something that will be fixed when the editors make the final scrubbing
of ops errors codes.
