      "message": "nfs41: Add backchannel processing support to RPC state machine\n\nAdds rpc_run_bc_task() which is called by the NFS callback service to\nprocess backchannel requests.  It performs similar work to rpc_run_task()\nthough \"schedules\" the backchannel task to be executed starting at the\ncall_trasmit state in the RPC state machine.\n\nIt also introduces some miscellaneous updates to the argument validation,\ncall_transmit, and transport cleanup functions to take into account\nthat there are now forechannel and backchannel tasks.\n\nBackchannel requests do not carry an RPC message structure, since the\npayload has already been XDR encoded using the existing NFSv4 callback\nmechanism.\n\nIntroduce a new transmit state for the client to reply on to backchannel\nrequests.  This new state simply reserves the transport and issues the\nreply.  In case of a connection related error, disconnects the transport and\ndrops the reply.  It requires the forechannel to re-establish the connection\nand the server to retransmit the request, as stated in NFSv4.1 section\n2.9.2 \"Client and Server Transport Behavior\".\n\nNote: There is no need to loop attempting to reserve the transport.  If EAGAIN\nis returned by xprt_prepare_transmit(), return with tk_status \u003d\u003d 0,\nsetting tk_action to call_bc_transmit.  rpc_execute() will invoke it again\nafter the task is taken off the sleep queue.\n\n[nfs41: rpc_run_bc_task() need not be exported outside RPC module]\n[nfs41: New call_bc_transmit RPC state]\nSigned-off-by: Ricardo Labiaga \u003cRicardo.Labiaga@netapp.com\u003e\nSigned-off-by: Benny Halevy \u003cbhalevy@panasas.com\u003e\n[nfs41: Backchannel: No need to loop in call_bc_transmit()]\nSigned-off-by: Andy Adamson \u003candros@netapp.com\u003e\nSigned-off-by: Ricardo Labiaga \u003cRicardo.Labiaga@netapp.com\u003e\nSigned-off-by: Benny Halevy \u003cbhalevy@panasas.com\u003e\n[rpc_count_iostats incorrectly exits early]\nSigned-off-by: Ricardo Labiaga \u003cRicardo.Labiaga@netapp.com\u003e\nSigned-off-by: Benny Halevy \u003cbhalevy@panasas.com\u003e\n[Convert rpc_reply_expected() to inline function]\n[Remove unnecessary BUG_ON()]\n[Rename variable]\nSigned-off-by: Ricardo Labiaga \u003cRicardo.Labiaga@netapp.com\u003e\nSigned-off-by: Benny Halevy \u003cbhalevy@panasas.com\u003e\n"
