[Qemu-block] [PATCH for-2.12 04/12] qemu-iotests: Enable 025 for luks


From: Kevin Wolf
Subject: [Qemu-block] [PATCH for-2.12 04/12] qemu-iotests: Enable 025 for luks
Date: Tue, 20 Mar 2018 18:36:24 +0100

We want to test resizing even for luks. The only change that is needed
is to explicitly zero out new space for luks because it's undefined.
