[lvm-devel] [PATCH LVM2] (7/12) update parallel_areas for on-going allocation

[Jun'ichi Nomura]

This patch adds _update_parallel_areas() to update parallel_areas list
based on the current allocation.

o For some cases (e.g. lvcreate), ah->parallel_areas weren't initialized.
  So now, _alloc_init() initialize it if there is none.
  build_parallel_areas() is allowed to return empty list.

o _update_parallel_areas() and other sub functions are added.
  It takes the range and PV then reflects them into existing parallel_areas.
