f83332a0d5 Several changes in udev rules:
- add DM_UDEV_RULES_VSN to provide a variable to be checked for in the other
  rules (e.g. to check that DM rules are actually installed, we can alternate
  functionality in the other rules based on this information, also we have
  versioning support for the rules)
- set proper sbin path for dmsetup and blkid, /sbin first, then /usr/sbin.
  This is necessary for anaconda to work properly.
- add 'last_rule' for cryptsetup's temporary devices (symlinks in /dev/mapper
  only)

2433909e20 Add daemons/cmirrord files to git - somehow got messed up with cvs rename.
When clogd was renamed to cmirrord, somehow git got the remove of the old
files but not the add of the new files.  This patch adds the new files.

a5609e3086 Update lvm_vg_write() to handle the deferred commit of lvm_vg_write().
Now that we've refactored the internal library functions that do the
vg_remove, we can handle the deferred commit of a lvm_vg_remove() inside
lvm_vg_write().  This makes the VG create/remove API more consistent in
terms of disk commits - they now both require an lvm_vg_write() to commit
the create or remove to disk.

43a1ea4e2f Update vg_remove_single_* functions to use the removed_pvs list.
Now that we've split vg_remove_single into two routines, in the first routine
that only manipulates memory, we move the PVs from the vg->pvs list to the
vg->removed_pvs list.  Then later, we iterate through this list to write the
removed PVs to disk, which removes them from the volume group and places them
into the internal ORPHAN VG.

d50795ed09 Split vg_remove_single into 2 functions - the second part commits to disk.
Split vg_remove_single into vg_remove_check (mandatory checks before
vgremove) and vg_remove (do actual remove by committing to disk).

In liblvm, we'd like to provide an consistent API that allows multiple
changes in memory, then let lvm_vg_write() control the commit to disk.  In
some cases (for example, lvresize calls fsadm) this may not be possible.
However, since we are using an object model and dividing things into small
operations, the most logical model seems to be the lvm_vg_write model, and
handling the special cases as they arrive.  So as best as possible
we move towards this end.

A possible optimization would be to consolidate vg_remove (committing)
code with vgreduce code.  A second possible optimization is making vgreduce
of the last device equivalent to vgremove.  Today, lvm_vg_reduce fails if
vgreduce is called with the last device, but from an object model perspective
we could view this as equivalent to vgremove and allow it.  My gut feel is
we do not want to do this though.

940077d030 Rename internal library function vg_remove to vg_remove_mdas.

3de6df8410 Enforce an alphabetical lock ordering for vgname locks.
Add a new constraint that vgname locks must be obtained in
alphabetical order.  At this point, we have test coverage for
the 3 commands affected - vgsplit, vgmerge, and vgrename.
Tests have been updated to cover these commands.
Going forward any command or library call that must obtain
more than one vgname lock must do so in alphabetical order.
Future patches will update lvm2app to enforce this ordering.

ae4ca998a3 Change vgsplit behavior to open/lock first vg based on alphabetical ordering.
If the destination vgname comes before the source vgname, we must open the
destination first because of the locking rules.  Thus, do a strcmp and set
the flag based on the comparison.

eb7c87e90d Refactor vgsplit - reorder _vgsplit_from and _vgsplit_to based on flag.
Slight functional change.  If we open the destination first, we cannot
know the 'fmt'.  In this case we use the default metadata type unless
the user has specified -M on the cmdline.  If not, in most cases this
is fine since we use the LVM2 default metadata type.  However, if the
user is specifying a non-default metadata type (e.g. lvm1) and the order
of the names is such that we have to open the destination (vg_to) first,
we have a problem.  So in this case, we require the use of -M and vgsplit
will fail with an error if not.  I've updated the man page to recommend
the usage of -M in this case.
