From f0490980a152958d25ce9762bfb296d8fd4c5512 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Fri, 8 Dec 2006 00:08:43 -0800 Subject: [PATCH] [NET]: Force a cache line split in hh_cache in SMP. hh_lock was converted from rwlock to seqlock by Stephen. To have a 100% benefit of this change, I suggest to place read mostly fields of hh_cache in a separate cache line, because hh_refcnt may be changed quite frequently on some busy machines.
