Indeed.  /me looks at the bond_check_dev_link callers more closely and 
shudders.

That wants fixing...

Note that netif_carrier_ok() can indeed be checked in interrupt context. 
  And if someone wants to send me patches converting more drivers to use 
netif_carrier_{on,off}, I would be very happy :)
