From ab6c7a0a43c2eaafa57583822b619b22637b49c7 Mon Sep 17 00:00:00 2001 From: Cong Wang Date: Sat, 29 Jun 2013 13:00:57 +0800 Subject: [PATCH] vti: remove duplicated code to fix a memory leak vti module allocates dev->tstats twice: in vti_fb_tunnel_init() and in vti_tunnel_init(), this lead to a memory leak of dev->tstats. Just remove the duplicated operations in vti_fb_tunnel_init(). (candidate for -stable) Cc: Stephen Hemminger Cc: Saurabh Mohan Cc: "David S.
