[PATCH] knfsd: nfsd4: fix setclientid_confirm cases
Setclientid_confirm code confused states 1 and 3 (numbering from the IMPLEMENTATION section of rfc3530, section 14.2.33). Fix this. State 1 allows the client to change the callback channel on the fly. We don't implement this currently, so just turn off the callback channel in this case. From: Fred Isaman Signed-off-by: J.
