3d37e976bf Fix pvcreate on a partition (regressed in 2.02.51).
Eliminate busy loop during pvcreate of a "normal" partition.
_md_sysfs_attribute_snprintf() would busy loop if the device it was
given was not a blkext-based MD partition.

Rather than being cute with a busy-loop prone 'goto check_md_major' in
_md_sysfs_attribute_snprintf(): explicitly check if the provided device
is a blkext-based partition (blkext_major()); and then check that the
get_primary_dev() determined parent is an MD device (md_major()).

e92d56a94d Retrieve MD sysfs attributes for MD partitions
Rename private _primary_dev() to a public get_primary_dev() and reuse it
to allow retrieval of the MD sysfs attributes (raid level, etc) for MD
partitions.

bb6a3a9608 Use the MD device's stripe-width, instead of chunk_size, to align the
data blocks of a Physical Volume that is placed directly upon an MD
device.

626dd7a5fe Suppress 'sb_offset' compiler warning by using enum for md superblock versions.
The warning is bogus and is only seen on certain versions of gcc.
However using the enum does seem to clarify the intent of the code - only
3 possible md minor superblock versions.

Related compiler warning:
