Subject: [PATCH AUTOSEL 6.6 030/139] l2tp: don't use tunnel socket sk_user_data in ppp procfs output
From: James Chapman <jchapman@...alix.com>
[ Upstream commit eeb11209e000797d555aefd642e24ed6f4e70140 ]
l2tp's ppp procfs output can be used to show internal state of
pppol2tp. It includes a 'user-data-ok' field, which is derived from
the tunnel socket's sk_user_data being non-NULL. Use tunnel->sock
being non-NULL to indicate this instead.
