[PATCH 14/27] l2tp: define parameters of l2tp_tunnel_find*() as "const"

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Guillaume Nault <g.nault@xxxxxxxxxxxx>

commit 2f858b928bf5a8174911aaec76b8b72a9ca0533d upstream.

l2tp_tunnel_find() and l2tp_tunnel_find_nth() don't modify "net".
