thanks to someone for pointing out to me my flub when i errantly
converted a spin_unlock to rtnl_lock (it in a very rarely, never
in fact as far as i know, used section of the code. this following
should now be even more correct.
[ATM]: use rtnl_{lock,unlock} during device operations
Are you sure nothing needs to walk the list in interrupt or softint
context? That's why you can't normally protect all of it using the
RTNL semaphore, because walks occur in non-sleepable contexts.
Read the comment above dev_base in drivers/net/Space.c to see what
the intended locking model is.
