[PATCH nf-next 11/15] netfilter: ipvs: prepare for hook function reduction

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Florian Westphal <fw@xxxxxxxxx>

ipvs has multiple one-line wrappers for hooks, compact them.

To avoid a large patch make the two most common helpers use the same
function signature as hooks.

Next patches can then remove the oneline wrappers.
