Chuck Lever 9995237bba svcrdma: Skip put_page() when send_reply() fails ...

Aug 18 17:00:37 klimt kernel: RIP: 0010:[<ffffffffa05c21c1>] svc_rdma_sendto+0x641/0x820 [rpcrdma] send_reply() assigns its page argument as the first page of ctxt. On error, send_reply() already invokes svc_rdma_put_context(ctxt, 1); which does a put_page() on that very page. No need to do that again as svc_rdma_sendto exits.
