Ming Lei 8f3d5686a2 ublk: don't allow user copy for unprivileged device ... commit 42aafd8b48adac1c3b20fe5892b1b91b80c1a1e6 upstream. UBLK_F_USER_COPY requires userspace to call write() on ublk char device for filling request buffer, and unprivileged device can't be trusted. So don't allow user copy for unprivileged device.
