[lvm-devel] [PATCH mirror 6/13] remove_mirror_images() to cope with stacked mirror

[Jun'ichi Nomura]

Change remove_mirror_images()
  - take LV as an argument, instead of LV segment, because segment-lv
    relationship could change after the layer removal
  - to cope with the stacked mirror LV, check the difference between
    lv_mirror_count() and seg->area_count.
    Iterate in this way: remove legs from the top-level mirror, if
    the mirror is turned to linear, collapse one layer and restart
    with remainder.

Thanks,
