File 0016-linux-user-Ignore-broken-loop-ioctl.patch of Package qemu
From: Alexander Graf <agraf@suse.de> Date: Tue, 12 Jun 2012 04:41:10 +0200 Subject: linux-user: Ignore broken loop ioctl MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 8bit During invocations of losetup, we run into an ioctl that doesn't exist. However, because of that we output an error, which then screws up the kiwi logic around that call. So let's silently ignore that bogus ioctl.
