The recvfrom methods must always call svc_xprt_received on completion so that the socket gets re-queued if there is any more work to do. This particular path did not make that call because it actually destroyed the svsk, making requeue pointless. When the svc_delete_socket was change to just set a bit, we should have added a call to svc_xprt_received, This is the problem that b0401d7253 attempted to fix, incorrectly. Signed-off-by: J.
