From 13f6a91479b06133eb99f1f43be02608eb867313 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Tue, 27 Nov 2012 18:54:21 +0100 Subject: target/configfs: use kmalloc() instead of kzalloc() for default groups All elements are assigned even the NULL member at the end so there is no reason to allocate zeroed memory.
