From 53576d9b995605a9edc7414b900a9218c8f23b1f Mon Sep 17 00:00:00 2001 From: Al Viro Date: Tue, 26 Sep 2006 22:18:43 -0700 Subject: [PATCH] [IPV4]: inetpeer annotations This one is interesting - we use net-endian value as search key, but order the tree by *host-endian* comparisons of keys. OK since we only care about lookups. Annotated inet_getpeer() and friends. Signed-off-by: Al Viro Signed-off-by: David S.
