Subject: net: ipv6: add net argument to ip6_dst_lookup_flow
|
||||
Origin: https://git.kernel.org/linus/c4e85f73afb6384123e5ef1bba3315b2e3ad031e
|
||||
|
||||
This will be used in the conversion of ipv6_stub to ip6_dst_lookup_flow,
|
||||
as some modules currently pass a net argument without a socket to
|
||||
ip6_dst_lookup. This is equivalent to commit 343d60aada5a ("ipv6: change
|
||||
ipv6_stub_impl.ipv6_dst_lookup to take net argument").
