d8ff1b1efb Fix warning for pvcreate over MD linear.
If MD linear device has set rounding (overload chunk size attribute),
the pvcreate command prints this warning:

  /dev/md0 sysfs attr level not in expected format: linear

c08c564e21 Use new dev_open_readonly fn to prevent opening devices for read-write when not necessary.
Before, we used vg_write_lock_held call to determnine the way a device is
opened. Unfortunately, this opened many devices in RW mode when it was not
really necessary. With the OPTIONS+="watch" rule used in the udev rules,
this could fire numerous events while closing such devices (and it caused
useless scans from within udev rules in return).

A common bug we hit with this was with the lvremove command which was unable
to remove the LV since it was being opened from within the udev rules. This
patch should minimize such situations (at least with respect to LVM handling
of devices).

Though there's still a possibility someone will open a device 'outside' in
parallel and fire the event based on the watch rule when closing a device
once opened for RW.

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.
