From ceaa79c434044e40031585a65a4e45dc09322e8f Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Fri, 26 Oct 2007 22:56:12 -0700 Subject: [PATCH] [NETNS]: Fix get_net_ns_by_pid The pid namespace patches changed the semantics of find_task_by_pid without breaking the compile resulting in get_net_ns_by_pid doing the wrong thing. So switch to using the intended find_task_by_vpid. Combined with Denis' earlier patch to make netlink traffic fully synchronous the inadvertent race I introduced with accessing current is actually removed. Signed-off-by: Eric W.
