Unfortunately, because it was a preexisting lock that just happened to be taken in the right spots we neglected to take it in dev_change_name. The race can affect calles of __dev_get_by_name that do so without taking the RTNL. They may end up walking down the wrong hash chain and end up missing the device that they're looking for.
