[PATCH] knfsd: Allow lockd to drop replies as appropriate
It is possible for the ->fopen callback from lockd into nfsd to find that an answer cannot be given straight away (an upcall is needed) and so the request has to be 'dropped', to be retried later. That error status is not currently propagated back. So: Change nlm_fopen to return nlm error codes (rather than a private protocol) and define a new nlm_drop_reply code. Cause nlm_drop_reply to cause the rpc request to get rpc_drop_reply when this error comes back. Cause svc_process to drop a request which returns a status of rpc_drop_reply.
