4059d2219c Recognise DRBD device part and handle it similar to MD devices.
The DRBD uses underlying device so code should prefer top
device if duplicate is found.

Patch also introduce
        dev_subsystem_part_major and dev_subsytem_name
functions to easily handle all these replication susbystems
and not hardcode md_major call.

See https://bugzilla.redhat.com/show_bug.cgi?id=530881
for full problem description.

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()).

08f0d365fd Add extended device (blkext) and MD partition (mdp) types to filters.
Both types were added with a 'max_partitions' of 1 because these devices
are _not_ partitionable (they are the partitions).

1a5d6bd23d Detect stream write failure reliably; new fn: lvm_fclose; use dm_fclose
* lib/misc/lvm-file.c (lvm_fclose): New function.
* lib/misc/lvm-file.h (lvm_fclose): Declare it.
* lib/config/config.c (write_config_file): Use the new function to detect
and diagnose unlikely write failure.
* lib/filters/filter-persistent.c (persistent_filter_dump): Likewise.
* lib/format_text/archive.c (archive_vg): Likewise.
* lib/format_text/format-text.c (_vg_write_file): Likewise.
* lib/log/log.c (fin_log): Similar, but use dm_fclose directly.
Include "\n" at end of each fprintf format string.

c93e6b5f79 Introduce is_same_inode macro, now including a comparison of st_dev.
* lib/misc/lvm-file.h (is_same_inode): Define.
* lib/filters/filter-persistent.c (persistent_filter_dump): Use is_same_inode
in place of a direct st_ino-only comparison.
* lib/locking/file_locking.c (_release_lock, _lock_file): Likewise.
