From: Cong Wang <[email protected]>
Introduce a generic IP address type, union inet_addr, so that
subsystems don't have to use their own definitions. Because
netpoll already defines union inet_addr, just move it to global.
Some of the helper functions will be used by VXLAN IPv6 code too.
This patch also reuses the "%pIS" specifier, to make it accept
union inet_addr instead of struct sockaddr.

Changing %pIS to %pIA is pure churn, and of zero value that I can see.
Every time I review this patch set I discover some new thing that I'm
very disappointed with.
You're going to have to stop being so ambitious, and start very small.
Maybe one tiny patch at a time if needed.

'S' in %pIS is for Sockaddr, since this patch makes it accept union
inet_addr instead of struct sockaddr, I don't think 'S' is meaningful
any more.

The "%pIS" change exists in v1, I don't know why you think it is new in
v2. Also, if you can point all what you dislike at one time, it would
save time for both of us, I prefer to fix them all in one update.

Ok, I will split the %pIS change from this patch.
Thanks!
