Chuck Lever 4500632f60 nfsd: Lower NFSv4.1 callback message size limit ... The maximum size of a backchannel message on RPC-over-RDMA depends on the connection's inline threshold. Today that threshold is typically 1024 bytes, making the maximum message size 996 bytes. The Linux server's CREATE_SESSION operation checks that the size of callback Calls can be as large as 1044 bytes, to accommodate RPCSEC_GSS. Thus CREATE_SESSION fails if a client advertises the true message size maximum of 996 bytes. But the server's backchannel currently does not support RPCSEC_GSS. The actual maximum size it needs is much smaller. It is safe to reduce the limit to enable NFSv4.1 on RDMA backchannel operation. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Signed-off-by: J.
