File tests-stop-using-private-dev-directory-for-losetup.patch of Package parted.30108

Subject: tests: stop using private "dev" directory for losetup
For: upstream code
Patch-mainline: v3.2
Git-commit: 478e472bf9f1c76b66a35ea75b45110152e5207d

Something about Fedora 17's losetup changed so that using a private
dev directory no longer worked.  Now, simply use /dev/ directly.
* tests/t-lvm.sh: Don't use $G_dev_.  Not needed, and actually
caused the t6000-dm root-only test to fail on Fedora 17.
Also, redirect less to stderr: that helps diagnose failure.

Acked-by: Sebastian Parschauer <sparschauer@suse.de>
