Pretty sure this is the same one I saw the other day when I applied
the old netns patches from Johannes. Johannes then fixed them, but not
sure if the new shiny patch was posted.
John, I think its best we just revert your current netns patches and
apply Johannes' new ones. That would mean not needing my ath9k oops
fix nor a secondary patch to fix this separately.
