[PATCH net 0/3] ipvlan: Deduplicate ipv4/ipv6 addr_validator_event code

[PATCH net 0/3] ipvlan: Deduplicate ipv4/ipv6 addr_validator_event code

[Dmitry Skorodumov]

This is a bit stylish patches: The code to handle ipv4 and ipv6
address change are exactly the same. We don't need separate
functions for them. Just look whether we are called
with ipvlan_addr4_notifier_block or with ipvlan_addr6_notifier_block

The changed functionality is already covered
with existing selftests/net/ipvtap_test.sh

[PATCH net 1/3] ipvlan: const-specifier for functions that use iaddr

[Dmitry Skorodumov]

Fix functions that accept "void *iaddr" as param to have
const-specifier.

[PATCH net 2/3] ipvlan: Common code from v6/v4 validator_event

[Dmitry Skorodumov]

Extract commond code for ipvlan_addr4_validator_event()/
ipvlan_addr6_validator_event() to own function.

Get rid of separate functions for xxx_validator_event()
and check whether we are called for ipv4 or ipv6 by

[PATCH net 3/3] ipvlan: common code to handle ipv6/ipv4 address events

[Dmitry Skorodumov]

Both IPv4 and IPv6 addr-event functions are very similar. Refactor
to use common funcitons.

Get rid of separate functions for ipvlan_addrX_event()
and check whether we are called for ipv4 or ipv6 by
looking at "notifier_block *nblock" argument
