5e84cb560d 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.

fa28cea152 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.

e4cdc051a9 Don't log an error if we can't write the cache file because the FS is read-only. 
Gets rid of that annoying error at shutdown.

63875e7591 Merge with text format branch. 
Lots of changes/very little testing so far => there'll be bugs!

Use 'vgcreate -M text' to create a volume group with its metadata stored
in text files.  Text format metadata changes should be reasonably atomic,
with a (basic) automatic recovery mechanism if the system crashes while a
change is in progress.

Add a metadata section to lvm.conf to specify multiple directories if
you want (recommended) to keep multiple copies of the metadata (eg on
different filesystems).

e.g. metadata {
        dirs = ["/etc/lvm/metadata1","/usr/local/lvm/metadata2"]
}

Plenty of refinements still in the pipeline.

1f8e695802 o It's a bit of a hack, but the regex filter now makes sure a device path 
that passed the filter is at the front of the aliases list.

d076caf473 o use dev_name(dev) to get the name of a device, this operation is cheap 
since it just get's the first alias.

e2b0745882 o composite filter that allows us to merge filters. Think of it as &&'ing 
filters in order.

eg,

	f = composite_filter_create(2, regex_filter, persistent_filter);

  ownership of the filters passes, they will be destroyed when f's
  destroy method is called.

92e804fc50 o Filter which caches valid devices in a file. Pass in init == 1 to the 
constructor if you want it to ignore the existing cache and check every
  device again (eg, vgscan, pvscan).
