[libvirt] [PATCH 00/12 v6] Unprivleged SG_IO support



As a result of RFC [1], this implements the unprivleged SG_IO
support.

v4 - v5:
   * Per discussion in [2], this set uses a hash table to
     store the shared disk's info. See 1/12 for more
     details.

Osier Yang (12):
  qemu: Add a hash table for the shared disks
  docs: Add docs and rng schema for new XML cdbfilter
  conf: Parse and format the new XML tag cdbfilter
  util: Prepare helpers for unpriv_sgio setting
  qemu: Manage disk's unpriv_sgio in domain lifecyle
  qemu: Do not restore the sysfs unpriv_sgio if the disk is being
    shared
  qemu: Error out when domain starting if the cdbfilter setting
    conflicts
  qemu: Set unpriv_sgio when attaching disk
  qemu: Restore unpriv_sgio when detaching disk
  qemu: Error out if the shared disk conf conflicts with others when
    attaching
  qemu: Do not restore unpriv_sgio when detaching disk if it's still
    shared
  conf: Save disk's original unpriv_sgio state into status XML
