Seems like a good idea too.
Ok, great.
Stephen, I think we need to find a way to put the device
registration call outside of the RTNL semaphore. I removed
in the unregister case, but to be complete we have to push it out in
the register path too.
The reason for all of these issues is that link_watch grabs the RTNL
semaphore, and this runs via keventd. Thus, trying to invoke any
usermode helper (/sbin/hotplug etc.) while holding the RTNL semaphore
can deadlock.
