NFSD: TEST_STATEID should not return NFS4ERR_STALE_STATEID
According to RFC 5661, the TEST_STATEID operation is not allowed to
return NFS4ERR_STALE_STATEID. In addition, RFC 5661 says:
15.1.16.5. NFS4ERR_STALE_STATEID (Error Code 10023)
A stateid generated by an earlier server instance was used. This
error is moot in NFSv4.1 because all operations that take a stateid
MUST be preceded by the SEQUENCE operation, and the earlier server
instance is detected by the session infrastructure that supports
SEQUENCE.
I triggered NFS4ERR_STALE_STATEID while testing the Linux client's
NOGRACE recovery. Bruce suggested an additional test that could be
useful to client developers.
Lastly, RFC 5661, section 18.48.3 has this:
o Special stateids are always considered invalid (they result in the
error code NFS4ERR_BAD_STATEID).
An explicit check is made for those state IDs to avoid printk noise.
