From e3eaa9910b380530cfd2c0670fcd3f627674da8a Mon Sep 17 00:00:00 2001 From: Jan Engelhardt Date: Wed, 17 Jun 2009 22:14:54 +0200 Subject: netfilter: xtables: generate initial table on-demand The static initial tables are pretty large, and after the net namespace has been instantiated, they just hang around for nothing. This commit removes them and creates tables on-demand at runtime when needed. Size shrinks by 7735 bytes (x86_64).
