From f6b72b6217f8c24f2a54988e58af858b4e66024d Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Thu, 14 Jul 2011 07:53:20 -0700 Subject: net: Embed hh_cache inside of struct neighbour. Now that there is a one-to-one correspondance between neighbour and hh_cache entries, we no longer need: 1) dynamic allocation 2) attachment to dst->hh 3) refcounting Initialization of the hh_cache entry is indicated by hh_len being non-zero, and such initialization is always done with the neighbour's lock held as a writer.
