But I bet actually at least ipv6 > can be a loadable module here, I'll take a look. Here's a fix that should help quite a bit with ipv6 as a loadable module. Regards, Tony 8< --------------------- From: Tony Lindgren <tony@xxxxxxxxxxx> Date: Mon, 27 Oct 2014 09:00:21 -0700 Subject: [PATCH] ARM: omap2plus_defconfig: Fix bloat caused by having ipv6 built-in Commit 673ce00c5d6c (ARM: omap2plus_defconfig: Add support for distros with systemd) caused considerable bloat as noted by Paul Walmsley <paul@xxxxxxxxx>. Let's fix this issue by making what we can into loadable modules for the systemd options. That's only IPV6 and AUTOFS4_FS it seems, and IPv6 defaults to a loadable module.
