	The 3 patches for IPVS look correct but this change
is already not needed after one of our planned changes:

"ipvs: reduce sync rate with time thresholds"

	Not sure how we will avoid the collision, may be
Simon will take only the other 2 changes? Or David will
take all changes and we have to rebase?
