From ec464e5dc504a164c5dbff4a06812d495e44e34d Mon Sep 17 00:00:00 2001 From: Patrick McHardy Date: Wed, 17 Apr 2013 06:47:08 +0000 Subject: [PATCH] netfilter: rename netlink related "pid" variables to "portid" Get rid of the confusing mix of pid and portid and use portid consistently for all netlink related socket identities.
