Adrian is this the correct way to constrain the selection between
"n" and "m" in this kind of situation? I thought doing something
like "depends on IPV6" is sufficient to achieve that?
"depends on IPV6" would fix the bug - but it would also make NF_CONNTRACK_H323 unavailable for all people without IPV6 support in their kernel.
Yes, that is an issue.

I guess with some slightly ugly ifdefs we could support the
whole matrix of possibilities. But perhaps that's undesirable
for another reason.
...

This depends on what NF_CONNTRACK_H323=y, IPV6=m is supposed to be:
- not allowed (NF_CONNTRACK_H323 must be modular) or
- NF_CONNTRACK_H323 can only be used for IPV4

My patch implements the first case.

Sorry for the slow reponse. This bug only came up due to my
bad gfs2/dlm patch, which Adrian has now corrected, so I think
you can just drop this patch. It now builds for me with only
Adrian's gfs2/dlm patch applied.
