[libvirt] [PATCH 0/9] Storage cloning for LVM and Disk backends

[Cole Robinson <crobinso redhat com>]

This following series implements cloning for LVM and disk backends. Most
of the functionality is already here, it just needed some reorganization
to be accessible for every backend.

I verified the following scenarios produced a bootable image:

- Clone within a disk pool
- Clone within a logical pool
- Clone a raw file to a disk pool
- Clone a disk pool to a logical pool

Cole Robinson (9):
  storage: Refactor FS backend 'create' function choosing.
  storage: Always assume we are tracking alloc progress in FS backend
  storage: Move most of the FS creation functions to common backend.
  storage: cleanup: do away with 'createFile'
  storage: Break out actual raw cloning to separate function.
  storage: Implement 'CreateBlockFrom' helper.
  storage: Don't try sparse detection if writing to block device.
  storage: Implement CreateVolFrom for logical and disk backend.
  storage: Fix deadlock when cloning across pools.
