Re: [PATCH net v3 1/3] ipv6: serialize address publication with device teardown

[Daehyeon Ko]

You are right. I overlooked both earlier comments. V4 drops the preliminary
READ_ONCE() conversions and the disable_ipv6 recheck. The new locking now
serializes only idev->dead, the state relevant to the reference leak, and
leaves the existing preliminary checks unchanged. Sorry for the churn.
