[Qemu-block] [PULL 3/5] iotests: Fix test 128 for password-less sudo


From: Kevin Wolf
Subject: [Qemu-block] [PULL 3/5] iotests: Fix test 128 for password-less sudo
Date: Fri, 2 Oct 2015 14:50:56 +0200

From: Max Reitz <address@hidden>

As of 934659c460d46c948cf348822fda1d38556ed9a4, $QEMU_IO is generally no
longer a program name, and therefore "sudo -n $QEMU_IO" will no longer
work.

Fix this by copying the qemu-io invocation function from common.config,
making it use $sudo for invoking $QEMU_IO_PROG, and then use that
function instead of $QEMU_IO.
