From 8f49ce1135676e5790d8ac5f8ecb2a218c07a33a Mon Sep 17 00:00:00 2001 From: Ben Pfaff Date: Mon, 25 Nov 2013 10:41:28 -0800 Subject: [PATCH] openvswitch: Shrink sw_flow_mask by 8 bytes (64-bit) or 4 bytes (32-bit). We won't normally have a ton of flow masks but using a size_t to store values no bigger than sizeof(struct sw_flow_key) seems excessive. This reduces sw_flow_key_range and sw_flow_mask by 4 bytes on 32-bit systems. On 64-bit systems it shrinks sw_flow_key_range by 12 bytes but sw_flow_mask only by 8 bytes due to padding. Compile tested only.
