From 65a18ec58e5e6186103f62f720acea94dfb26f4e Mon Sep 17 00:00:00 2001 From: "Denis V. Lunev" Date: Wed, 16 Apr 2008 01:59:46 -0700 Subject: [PATCH] [NETNS]: Add netns refcnt debug for kernel sockets. Protocol control sockets and netlink kernel sockets should not prevent the namespace stop request. They are initialized and disposed in a special way by sk_change_net/sk_release_kernel.
