And remaining of netdev tracking patches would be
b445498bdb7a net: eql: add net device refcount tracker
2702cdbf4a6d vlan: add net device refcount tracker
1f1ef25dabe9 net: bridge: add net device refcount tracker
e418e7268655 net: watchdog: add net device refcount tracker
b08577d21d47 net: switchdev: add net device refcount tracker
57f014dc36db inet: add net device refcount tracker to struct fib_nh_common
a51ab6e951ea ax25: add net device refcount tracker
cd494c182dcb llc: add net device refcount tracker
9572141ddb29 pktgen add net device refcount tracker
d0b171bbc275 net/smc: add net device tracker to struct smc_pnetentry
c335545a38c0 netlink: add net device refcount tracker to struct ethnl_req_info
4bb89c4fef19 openvswitch: add net device refcount tracker to struct vport
86957122aab2 net: sched: act_mirred: add net device refcount tracker
I think the most important one for the leaks would be the " inet: add
net device refcount tracker to struct fib_nh_common"
