Log message:
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.

Version 2.02.28 -
-================================
+ Introduce is_same_inode macro, now including a comparison of st_dev.
Don't leak a file descriptor in _lock_file(), when flock fails.
Add SUN's LDOM virtual block device to filters
Split metadata-external.h out from metadata.h for the tools to use.
