    I have now run more extensive Syzkaller testing on following patches:

    cb626bf566eb net-sysfs: Fix reference count leak
    ddd9b5e3e765 net-sysfs: Call dev_hold always in rx_queue_add_kobject
    e0b60903b434 net-sysfs: Call dev_hold always in netdev_queue_add_kobje
    48a322b6f996 net-sysfs: fix netdev_queue_add_kobject() breakage
    b8eb718348b8 net-sysfs: Fix reference count leak in rx|netdev_queue_add_kobject

    These patches are fixing couple of memory leaks including this one found
    by Syzbot: https://syzkaller.appspot.com/bug?extid=ad8ca40ecd77896d51e2

    I can reproduce these memory leaks in following stable branches: 4.14,
    4.19, and 5.4.

    These are all now merged into net/master tree and based on my testing
    they are ready to be taken into stable branches as well.

    Best Regards,

    Jouni Högander
