[IPVS]: Add and reorder bh locks after moving to keventd.
An addition to the last ipvs changes that move update_defense_level/si_meminfo to keventd: - ip_vs_random_dropentry now runs in process context and should use _bh locks to protect from softirqs - update_defense_level still needs _bh locks after si_meminfo is called, for the same purpose Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>
