NLM: Fix sparse warnings

2007-05-14T23:33:46+00:00

 - fs/lockd/xdr4.c:140:27: warning: incorrect type in argument 2 (different
   explicit signedness)
 - fs/lockd/xdr4.c:141:27: warning: incorrect type in argument 2 (different
   explicit signedness)
 - fs/lockd/xdr4.c:432:28: warning: incorrect type in argument 2 (different
   explicit signedness)
 - fs/lockd/xdr4.c:433:28: warning: incorrect type in argument 2 (different
   explicit signedness)
 - fs/lockd/xdr4.c:587:20: warning: symbol 'nlm_version4' was not declared.
   Should it be static?

lockd: pass cookie in nlmsvc_testlock

2007-05-07T00:38:50+00:00

Change NLM internal interface to pass more information for test lock; we
need this to make sure the cookie information is pushed down to the place
where we do request deferral, which is handled for testlock by the
following patch.

lockd: save lock state on deferral

2007-05-07T00:38:50+00:00

We need to keep some state for a pending asynchronous lock request, so this
patch adds that state to struct nlm_block.

This also adds a function which defers the request, by calling
rqstp->rq_chandle.defer and storing the resulting deferred request in a
nlm_block structure which we insert into lockd's global block list.  That
new function isn't called yet, so it's dead code until a later patch.

NLM: Shrink the maximum request size of NLM4 requests

2007-05-01T05:17:09+00:00

NLM version 4 requests estimate the call and reply header sizes rather
conservatively, using the very maximum size allowed in the protocol even
though Linux always uses only a small fraction of the allowable space.

Reduce the size of caller and lock arguments to conserve RPC buffer space
while XDR encoding NLM4 arguments.  Add compile-time checks to ensure the
hostname string won't overflow NLM protocol maximums.

[PATCH] knfsd: Allow lockd to drop replies as appropriate

2006-10-17T15:18:46+00:00

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.
