File tests-check-extended-partition-length.patch of Package parted.15765

From: "Brian C. Lane" <bcl@redhat.com>
Date: Fri, 5 Jun 2015 13:46:29 -0700
Subject: tests: Make sure the extended partition length is correct
For: libparted-BLKPG_RESIZE_PARTITION-uses-bytes.patch
References: bsc#1058667
Patch-mainline: v3.3
Git-commit: 31b5bfa4cd0b2e2944af22466e7b7d88ad94c4c9

parted tells the kernel the wrong length when reporting a resize of an
extended partition. Make sure the length is 2 for 512b sectors and 1
sector for larger.
Acked-by: Sebastian Parschauer <sparschauer@suse.de>
