Date: Fri, 26 Oct 2007 17:29:41 -0600 From: ebiederm@...ssion.com (Eric W. Biederman) To: David Miller <davem@...emloft.net> CC: <netdev@...r.kernel.org>, Linux Containers <containers@...ts.osdl.org>, "Denis V. Lunev" <dlunev@...il.com>, Benjamin Thery <benjamin.thery@...l.net>, Daniel Lezcano <dlezcano@...ibm.com> 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.
