rpc: changes to glusterfs programs that can take an optional payload argument.

2010-08-06T10:37:20+00:00

- The existing interface required the transport to separate the procedure
    header and procedure payload into two different buffers. Making this
    separation can prove cumbersome for transports like rdma wherein the header
    and payload can be received in a single buffer (For eg., header and payload
    of write fop sent as inline msg using rdma-send). This patch delegates the
    responsiblity of separating out header and payload to programs.

changes to rpc

2010-07-28T12:08:26+00:00

- use mem-pool for requests and saved_frames.
  - preserve the rpc_req structure till rpc invokes program's reply.
    This will enable us to store transport specific data that has to
    last till reply has come (eg., memory regions of chunk lists in
    case of rdma).
  - change signature of rpc_clnt_submit to accept rsphdr_vector and
    rsppayload_vector. The buffers pointed by these vectors will be
    from iobufs and these iobufs are added to an iobref which should
    also be passed as an arguement to rpc_clnt_submit.
