| H A D | svc_xprt.h | 3c45ddf8 Wed Jul 16 14:38:32 CDT 2014 Chuck Lever <chuck.lever@oracle.com> svcrdma: Select NFSv4.1 backchannel transport based on forward channel
The current code always selects XPRT_TRANSPORT_BC_TCP for the back
channel, even when the forward channel was not TCP (eg, RDMA). When
a 4.1 mount is attempted with RDMA, the server panics in the TCP BC
code when trying to send CB_NULL.
Instead, construct the transport protocol number from the forward
channel transport or'd with XPRT_TRANSPORT_BC. Transports that do
not support bi-directional RPC will not have registered a "BC"
transport, causing create_backchannel_client() to fail immediately.
