Subject: [PATCH v1 net-next 1/6] l2tp: Don't assign net->gen->ptr[] for pppol2tp_net_ops.
Date: Mon, 29 Jul 2024 14:07:56 -0700	[thread overview]
Message-ID: <20240729210801.16196-2-kuniyu@amazon.com> (raw)
In-Reply-To: <20240729210801.16196-1-kuniyu@amazon.com>

Commit fd558d186df2 ("l2tp: Split pppol2tp patch into separate l2tp and
ppp parts") converted net->gen->ptr[pppol2tp_net_id] in l2tp_ppp.c to
net->gen->ptr[l2tp_net_id] in l2tp_core.c.

Now the leftover wastes one entry of net->gen->ptr[] in each netns.

Let's avoid the unwanted allocation.

Fixes: fd558d186df2 ("l2tp: Split pppol2tp patch into separate l2tp and ppp parts")
