      qed: Consistency check support · 01979a98
      Stefan Hajnoczi authored
      This patch adds support for the qemu-img check command.  It also
      introduces a dirty bit in the qed header to mark modified images as
      needing a check.  This bit is cleared when the image file is closed
      cleanly.
      
      If an image file is opened and it has the dirty bit set, a consistency
      check will run and try to fix corrupted table offsets.  These
      corruptions may occur if there is power loss while an allocating write
      is performed.  Once the image is fixed it opens as normal again.
