From c0453377518d8dd30dcc07b5bdd9e29512ca9aca Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Mon, 30 Oct 2017 17:19:25 -0500 Subject: netfilter: ipset: use swap macro instead of _manually_ swapping values Make use of the swap macro and remove unnecessary variables tmp. This makes the code easier to read and maintain. This code was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R.
