static int __init libfcoe_init(void)
{
        int rc = 0;

        rc = fcoe_transport_init();
        if (rc)
                return rc;

        rc = fcoe_sysfs_setup();
        if (rc)
                fcoe_transport_exit();    <=============

        return rc;
}

It is called from __init context here.




static void __exit libfcoe_exit(void)
{
        fcoe_sysfs_teardown();
        fcoe_transport_exit();     <==============
}

And from __exit context here.
This is -rc1.
