Subject: tests: Add /dev/md/ check to t6100
For: libparted-canonicalize-dev-md-paths.patch
References: bsc#1078820
Patch-mainline: submitted, 2018-02-20
The test t6100 checks creating two partitions with /dev/md99 and
a gpt disk label. But using an md name with the symlink in /dev/md/
is not tested. That path might not be canonicalized and the BLKPG*
handling cannot find the existing partitions in /sys/block/$dev/.
That can be observed when creating the second partition while the
first one is in use.
So move common code to new functions create_mddev() and
remove_mdparts(), check if the swap tools are available, retest with
/dev/md/pedtest99, msdos disk label, and the first partition as swap.
