File tests-wait_for_-loop.patch of Package parted.30108

From: "Brian C. Lane" <bcl@redhat.com>
Date: Tue, 1 Mar 2016 10:38:26 -0800
Subject: tests: Add udevadm settle to wait_for_ loop (#1260664)
For: upstream code
Patch-mainline: v3.3
Git-commit: f5cc84cdb5a607449c339cad50fe8be5dd77eb6c

Sometimes the device will vanish after the wait_for_dev_to_appear exits.
Add udevadm settle in an attempt to make sure the udev system is done
flapping around and the device will stay in place.
