![]() When a connection is cancelled by p9_conn_cancel(), all requests on it should be cancelled---mark req->status as REQ_STATUS_ERROR. However, because a race over m->err between p9_conn_cancel() and p9_fd_request(), p9_fd_request might see the old value of m->err, think that the connection is NOT cancelled, and then add new requests to this cancelled connection. Fixing this issue by lock-protecting the check on m->err.
