Hello,
I've found it at last but on that occasion I've got some
doubt according to rcu_read_lock and rcu_call treatment:

Actually there is one more doubt (bug really, but
not very probable): proc file reading is without any
locking in fib_hash.c, so if somebody uses programs
which do that often, he could have problems while
adding or deleting a route in a wrong time. If it
will be ever changed, fz_nent should also be ++/--
under lock, I think.
