Hi all,

After merging the nfsd tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

net/sunrpc/xprtrdma/svc_rdma_backchannel.c: In function 'svc_rdma_handle_bc_reply':
net/sunrpc/xprtrdma/svc_rdma_backchannel.c:67:21: error: 'struct rpc_xprt' has no member named 'recv_lock'; did you mean 'reserve_lock'?
spin_unlock(&xprt->recv_lock);
^~~~~~~~~
reserve_lock
net/sunrpc/xprtrdma/svc_rdma_backchannel.c:79:19: error: 'struct rpc_xprt' has no member named 'recv_lock'; did you mean 'reserve_lock'?
spin_lock(&xprt->recv_lock);
^~~~~~~~~
reserve_lock

Caused by commit

cf4f6fd48dac ("svcrdma: Remove ->release_rqst call in bc reply handler")

interacting with commit

75c84151a9dc ("SUNRPC: Rename xprt->recv_lock to xprt->queue_lock")

from the nfs tree.

I have added the following merge fix patch for today:
