We have many EXPORT_SYMBOL(x) in networking tree because IPv6 can be built as a module. CONFIG_IPV6=y is becoming the norm. Define a EXPORT_IPV6_MOD(x) which only exports x for modular IPv6. Same principle applies to EXPORT_IPV6_MOD_GPL() Signed-off-by: Eric Dumazet <edumazet@google.com> --- include/net/ip.h | 8 ++++++++ 1 file changed, 8 insertions(+)
