From 1c98d2f439f3f945c5040fd648d817e86314f2fa Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Tue, 27 Nov 2012 18:54:19 +0100 Subject: [PATCH] target/configfs: allocate pointers instead of full struct for default_groups default_groups is defined as struct config_group **default_groups so we don't need to allocate a whole struct but only enough space for a pointer that points there.
