Subject: A one-liner ipvs patch

Hi!

I have a few very high connection rate services behind LVS and when
keepalived removes them because of problems, the LVS would be rebooted
with tens of thousands of this message in the logs (rebooted by hardware
watchdogs).

I have had it running on production systems for maybe 3 months or so and
this problem hasn't occured any more, which does not prove that the
patch isn't just curing a symptom, but I think it is concievable, that a
lot of printks could hang a system.

Siim
