From c97a72ea2ed78ad87b471447e498f7e09c6f7c85 Mon Sep 17 00:00:00 2001 From: Jesse Gross Date: Wed, 3 Oct 2012 11:29:05 -0700 Subject: [PATCH] flow: Fix struct flow size build assertion failure. The new struct flow_tnl contains an extra four bytes of padding on 64-bit machines but we currently assert that the total struct flow is a fixed size. The size difference isn't actually a problem because both are multiples of 4 and the build assertion is only intended to remind people to update FLOW_WC_SEQ when new fields are added. This changes the assertion to fix just the non-tunnel field size.
