Hi,

These patches do followings:

    [ 1/11] lvconvert takes '--wait' instead of '--background'

  - Add generalized upward link from LV to seg
    [ 2/11] Add upward link from underlying LV to stacked seg

  - Cosmetic changes for later bugfixes
    [ 3/11] Move mirror log initialization functions
    [ 4/11] Move _find_tmp_mirror()
    [ 5/11] Move removable_pvs checking

  - Fix mirror log addition/removal for LV under conversion
    [ 6/11] Export find_tmp_mirror()
    [ 7/11] lvconvert adds/removes mirror log to/from the original LV

  - Fix remove_mirror_images()
    [ 8/11] Allow "mirror" segment with only 1 area
    [ 9/11] _init_mirror_log() to cope with activation status
    [10/11] Fix _remove_mirror_images() to cope with stacked mirror
    [11/11] Fix _remove_mirror_images() to skip AREA_LV

  - Appendix: 2 test scripts for mirroring

Since the last week's patchset,

Done with the patch "2/11" of this series.

remove_mirror_images() didn't work nicely with non-empty
removable_pvs.
Fixed by patches "8/11" - "11/11".

This was not a problem.
