llapi_layout_get_by_fd() contains this code which uses lmm_stripe_count without first checking if the lov_user_md needs to be byte-swapped. This causes a false error on PowerPC clients.

        if (!S_ISDIR(st.st_mode) && object_count != lum->lmm_stripe_count) {
                errno = EINTR;
                goto out;
        }
