From 3f53a38131a4e7a053c0aa060aba0411242fb6b9 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Thu, 26 Feb 2009 03:35:13 -0800 Subject: ipv6: don't use tw net when accounting for recycled tw We already have a valid net in that place, but this is not just a cleanup - the tw pointer can be NULL there sometimes, thus causing an oops in NET_NS=y case. The same place in ipv4 code already works correctly using existing net, rather than tw's one. The bug exists since 2.6.27. Signed-off-by: Pavel Emelyanov Signed-off-by: David S.
