[PATCH 3.2 15/79] l2tp: purge session reorder queue on delete

[Ben Hutchings]

3.2.99-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Tom Parkin <tparkin@xxxxxxxxxxx>

commit 4c6e2fd35460208596fa099ee0750a4b0438aa5c upstream.

Add calls to l2tp_session_queue_purge as a part of l2tp_tunnel_closeall
and l2tp_session_delete.  Pseudowire implementations which are deleted only
via. l2tp_core l2tp_session_delete calls can dispense with their own code for
flushing the reorder queue.
