[lvm-devel] [PATCH mirror 6/13] Count the correct number of mirror images

[Jun'ichi Nomura]

If temporary mirror layers are inserted, you can't get
the number of mirror images by seg->area_count.

The patch adds a function to recursively sum up the number
of mirror images.
Used later by lvconvert and reporting functions.

Thanks,
