From 0895b08adeb3f660cdff21990d0a9c2b59a919e7 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Sat, 16 Jul 2011 17:36:53 -0700 Subject: [PATCH] neigh: Simply destroy handling wrt. hh_cache. Now that hh_cache entries are embedded inside of neighbour entries, their lifetimes and accesses are now synchronous to that of the encompassing neighbour object. Therefore we don't need to hook up the blackhole op to hh_output on destroy. Signed-off-by: David S.
