xprtrdma needs to allocate the Call and Reply buffers separately. TBH, the reliance on using a single buffer for the pair of XDR buffers is transport implementation-specific. Transports that want to allocate separate Call and Reply buffers will ignore the "size" argument anyway. Don't bother passing it. The buf_alloc method can't return two pointers. Instead, make the method's return value an error code, and set the rq_buffer pointer in the method itself. This gives call_allocate an opportunity to terminate an RPC instead of looping forever when a permanent problem occurs. If a request is just bogus, or the transport is in a state where it can't allocate resources for any request, there needs to be a way to kill the RPC right there and not loop. This immediately fixes a rare problem in the backchannel send path, which loops if the server happens to send a CB request whose call+reply size is larger than a page (which it shouldn't do yet). One more issue: looks like xprt_inject_disconnect was incorrectly placed in the failure path in call_allocate. It needs to be in the success path, as it is for other call-sites. Signed-off-by:

Clean up: there is some XDR initialization logic that is common to the forward channel and backchannel. Move it to an XDR header so it can be shared. rpc_rqst::rq_buffer points to a buffer containing big-endian data. Update its annotation as part of the clean up. Signed-off-by:

Use a setup function to call into the NFS layer to test an rpc_xprt for session trunking so as to not leak the rpc_xprt_switch into the nfs layer. Search for the address in the rpc_xprt_switch first so as not to put an unnecessary EXCHANGE_ID on the wire. Signed-off-by:

rpc_task_set_client is only called from rpc_run_task after rpc_new_task and rpc_task_release_client is not needed as the task is new. When called from rpc_new_task, rpc_task_set_client also removed the assigned rpc_xprt which is not desired. Signed-off-by:

Current NFSv4.1/pNFS client assumes that MDS supports only one layout type. While it's true for most existing servers, nevertheless, this can be change in the near future. For now, this patch just plumbs in the ability to track a list of layouts in the fsinfo structure. The existing behavior of the client is preserved, by having it just select the first entry in the list. Signed-off-by:
