Subject: [PATCH ipsec-next 0/3] xfrm: remove three xfrm_afinfo_policy indirections

This series removes three indirections from xfrm_afinfo_policy by
folding them into their callers.

1. Tos is a one-liner only needed by ipv4
2. init_path is also small and only needed by ipv6
3. decode_session has no dependencies on ipv6 or ipv4,
   fold it.

The remaining indirections are necessary in the CONFIG_IPV6=m
case.  Its possible to fold only the ipv4 part and handle ipv6
based on CONFIG_IPV6_{MODULE,BUILTIN} but that increases
complexity, so my intent is to go after indirections similar
to the ones folded here first.

Florian Westphal (3):
      xfrm: remove tos indirection from afinfo_policy
      xfrm: remove init_path indirection from afinfo_policy
      xfrm: remove decode_session indirection from afinfo_policy
