Hi,
These patches do followings:
- Change default behavior of lvconvert
[ 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

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.
