Eric Dumazet b2f72a4311 net: avoid weird emergency message ... [ Upstream commit d7c04b05c9ca14c55309eb139430283a45c4c25f ] When host is under high stress, it is very possible thread running netdev_wait_allrefs() returns from msleep(250) 10 seconds late. This leads to these messages in the syslog : [...] unregister_netdevice: waiting for syz_tun to become free. Usage count = 0 If the device refcount is zero, the wait is over.
