Just to update status of the issue. The key moment is that pppoe_flush_dev
may be called asynchronously (especially via sysfs on dev entry, for example
we retrieve mtu of device and while we at it other process may update mtu
via sysfs). So I'm returning pppoe_hash_lock back which should eliminate a
number of lock complains and make locking scheme easier. All-in-one: I'm
working on it. Just need some more time.
