9eab84aa2b debug: catch invalid request for tree
In general for non-toplevel LVs we shouldn't allow any _tree_action.

doesn't even exist in dm-table.

bd2500e62e libdm: track implicit dependecies
When the node enters dtree with implicit dependency, it
automatically has udev flags from parent node
and could not be changed later when the node has been
entered again via i.e lvm's preload tracking.

Resolve this by tracking whether the node has been
created by implicit dependency tracking or has been
entered explicitely. Implicit node could be later
upgraded by an explicit _add_dev() with proper udev_flags.

For implicit devices add special udev flags to avoid
any scan and udev rule processing if we resume such device.

Patch allows easier removing of orphan nodes.

6c6468f91d RAID: Improve an error message
When down-converting a RAID1 LV, if the user specifies too few devices,
they will get a confusing message.
Ex:
[root]# lvcreate -m 2 --type raid1 -n raid -L 500M taft
  Logical volume "raid" created

[root]# lvconvert -m 0 taft/raid /dev/sdd1
  Unable to extract enough images to satisfy request
  Failed to extract images from taft/raid

This patch makes the error message a bit clearer by telling the user
the count they are trying to remove and the number of devices they
supplied.

[root@bp-01 lvm2]# lvcreate --type raid1 -m 3 -L 200M -n lv vg
  Logical volume "lv" created

[root@bp-01 lvm2]# lvconvert -m -3 vg/lv /dev/sdb1
  Unable to remove 3 images:  Only 1 device given.
  Failed to extract images from vg/lv

[root@bp-01 lvm2]# lvconvert -m -3 vg/lv /dev/sd[bc]1
  Unable to remove 3 images:  Only 2 devices given.
  Failed to extract images from vg/lv

[root@bp-01 lvm2]# lvconvert -m -3 vg/lv /dev/sd[bcd]1
[root@bp-01 lvm2]# lvs -a -o name,attr,devices vg
  LV   Attr       Devices
  lv   -wi-a----- /dev/sde1(1)

This patch doesn't work in all cases.  The user can specify the right
number of devices, but not a sufficient amount of devices from the LV.
This will produce the old error message:
[root@bp-01 lvm2]# lvconvert -m -3 vg/lv /dev/sd[bcf]1
  Unable to extract enough images to satisfy request
  Failed to extract images from vg/lv
However, I think this error message is sufficient for this case.

0a15a210a5 cache: cache segment is non-discardable
Since cache segment is purely virtual mapping, it has nothing for
discard. Discardable is cache origin here which is now
properly removed on 'delete' phase.

Plain lv_empty() call needs to only detach cache origin and leave
origin unchanged.
