From: Al Viro Date: Wed, 27 Sep 2006 05:18:43 +0000 (-0700) Subject: [IPV4]: inetpeer annotations X-Git-Tag: v2.6.19-rc1~858^2~129 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=53576d9b995605a9edc7414b900a9218c8f23b1f;p=linux-2.6 [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.
