Perhaps ip_vs_conn_fill_param_sync_v1() would be a better name?

I think that you need the patch
"IPVS: Add persistence engine to connection entry" that I posted,
or something similar in your series in order for connection
templates with created by synchronisation to have the correct
persistence engine associated with them.

Please align line-wrapped parameters against the opening (
ip_vs_conn_fill_param(af, sc->protocol,
(const union nf_inet_addr *)&sc->caddr,
sc->cport,
(const union nf_inet_addr *)&sc->vaddr,
sc->vport, p);
Also several more times below.
This also applies to function definitions.
Actually, I think p_vs_conn_fill_param_sync_v0() can be
replaced by a direct call to ip_vs_conn_fill_param(). But
my comments regarding formatting still apply elsewhere.

I realise that the commenting syntax used throughout IPVS
is a) inconsistent and b) for the most part does not comply with
any variant of the style guidelines. However, for the record
I believe that the preferred commenting style for code in net/
and thus IPVS is:
/* This is a one line comment */
/* This is a
* multi-line comment
*/

I'm ok with not aligning to the opening ( in order to avoid
going over 80 columns here. Though I suspect others would disagree.

I think we can just replace this with a direct call to
ip_vs_conn_fill_param() and avoid the need for error checking.
The idea of the existing ip_vs_conn_fill_param_sync() was as a place holder.
But this patch fills in the relevant bits in the v1 version of that function.

There shouldn't be a space between '(' and 'm2'.
There should be a space either side of each '=='.

This cast seems nasty to me. Is it there to un-const buffer?
If so I think it would be better just remove the const qualification
from the parameter, as its clearly not being used in a const way.
The patch "IPVS: buffer argument to ip_vs_process_message() should not be const"
from my prototype series was my attempt to address this.
