xfrm: remove output indirection from xfrm_mode
Same is input indirection. Only exception: we need to export xfrm_outer_mode_output for pktgen. Increases size of vmlinux by about 163 byte: Before: text data bss dec filename 15730208 6936948 4046908 26714064 vmlinux After: 15730311 6937008 4046908 26714227 vmlinux xfrm_inner_extract_output has no more external callers, make it static. v2: add IS_ENABLED(IPV6) guard in xfrm6_prepare_output add two missing breaks in xfrm_outer_mode_output (Sabrina Dubroca) add WARN_ON_ONCE for 'call AF_INET6 related output function, but CONFIG_IPV6=n' case. make xfrm_inner_extract_output static Signed-off-by: Florian Westphal <fw@strlen.de> Reviewed-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com>
