From 713ef298e3d2055034c74e2a2e508e0eb1aad817 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Mon, 28 Mar 2011 13:22:26 +0300 Subject: fs-tests: integck: introduce zalloc The integck test often allocates memory and fills it with zeroes. Introduce a helper function for this frequent operation. This is just a clean-up patch which makes the code 23 lines shorter.
