[0]\n\nCommit eb28fd76c0a0 (\"gtp: Destroy device along with udp socket's netns\ndismantle.\") added the for_each_netdev() loop in gtp_net_exit_batch_rtnl()\nto destroy devices in each netns as done in geneve and ip tunnels.\n\nHowever, this could trigger ->dellink() twice for the same device during\n->exit_batch_rtnl().\n\nSay we have two netns A & B and gtp device B that resides in netns B but\nwhose UDP socket is in netns A.\n\n 1. cleanup_net() processes netns A and then B.\n\n 2. gtp_net_exit_batch_rtnl() finds the device B while iterating\n netns A's gn->gtp_dev_list and calls ->dellink().\n\n [ device B is not yet unlinked from netns B\n as unregister_netdevice_many() has not been called. ]\n\n 3. gtp_net_exit_batch_rtnl() finds the device B while iterating\n netns B's for_each_netdev() and calls ->dellink().\n\ngtp_dellink() cleans up the device's hash table, unlinks the dev from\ngn->gtp_dev_list, and calls unregister_netdevice_queue().\n\nBasically, calling gtp_dellink() multiple times is fine unless\nCONFIG_DEBUG_LIST is enabled.\n\nLet's remove for_each_netdev() in gtp_net_exit_batch_rtnl() and\ndelegate the destruction to default_device_exit_batch() as done\nin bareudp.\n\n[0]:\nlist_del corruption, ffff8880aaa62c00->next (autoslab_size_M_dev_P_net_core_dev_11127_8_1328_8_S_4096_A_64_n_139+0xc00/0x1000 [slab object]) is LIST_POISON1
