Subject: [Patch net v3 0/2] l2tp: fix race conditions in l2tp_tunnel_register()

From: Cong Wang <cong.wang@...edance.com>

This patchset contains two patches, the first one is a preparation for
the second one which is the actual fix. Please find more details in
each patch description.

I have ran the l2tp test (https://github.com/katalix/l2tp-ktest),
all test cases are passed.

v2: move IDR allocation to l2tp_tunnel_register()

Cong Wang (2):
  l2tp: convert l2tp_tunnel_list to idr
