If got you right, Paolo's commit introduced a regression, so we (I
guess you and Paolo) need to either solve it or we (community)
should consider a revert, please suggest.

[...] So, this issue should be
reproducible either after Paolo's commit or with any kernel prior to
your commit to use the skb->cb area to store the DGID, but it probably
requires the specific series of actions in this bug to trigger it.

mmm

A normal, clean shutdown of the interface doesn't demonstrate the issue.

so maybe @ least for the time being, we should be picking Hong's patch
with proper change log and without the giant stack dump till we have
something better. If you agree, can you do the re-write of the change
log?

Or.

The bug is now in stable and distro kernels, so please act.
