From dd5a1843d566911dbb077c4022c4936697495af6 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Thu, 7 Feb 2008 23:30:42 -0800 Subject: [PATCH] [IPSEC] flow: reorder "struct flow_cache_entry" and remove SLAB_HWCACHE_ALIGN 1) We can shrink sizeof(struct flow_cache_entry) by 8 bytes on 64bit arches. 2) No need to align these structures to hardware cache lines, this only waste ram for very litle gain.
