Because the func batadv_softif_init_late allocate some resources and it would be invoked in register_netdevice. So we need to invoke the func batadv_softif_free instead of free_netdev to cleanup when fail to register_netdevice.
I could be wrong, but shouldn't the destructor be replaced with
and the batadv_softif_free (without the free_netdev) used as ndo_uninit?
line you've changed should then be kept as free_netdevice.
At least this seems to be important when using rtnl_newlink() instead of
legacy sysfs netdev stuff from batman-adv. rtnl_newlink() would also only
free_netdevice and thus also not run batadv_softif_free. This seems to be
fixable by calling ndo_uninit.
Kind regards, Sven
Sorry, I don't get you. The net_dev is created in this func batadv_softif_create. Why couldn't invoke batadv_softif_free to cleanup when fail to register_netdevice?
