[lvm-devel] [PATCH pvmove 3/3] use generic mirror allocation for pvmove

[Jun'ichi Nomura]

Extent allocation code used to have special support for pvmove
since pvmove already knows PV area to use for mirrored segment.

This patch changes the pvmove's logic to the way similar to
what lvconvert does for mirrored LV.
Not only clean up the allocation code, it also allows
splitted allocation for destination areas.

Thanks,
