Oh, by the way, I forgot something important you spotted with the list
protected by the mutex.
When looking at ipv6/fib_hash.c with Benjamin, we need to browse the
network namespaces list for the garbage collecting, but we are in an
interrupt handler, so I can not use rtnl_lock.
where exactly....
all interesting places are called under rtnl already...
Why is not possible to protect the list with a simple spinlock ? so we
can call spin_lock_bh when we are in interrupt handler.
see my old patch with a locking rules :)
By the way, I have forgotten to mention, that the original patch works
from 2004 for OpenVz :)
