[lvm-devel] [PATCH LVM2] (8/12) 'anywhere' policy implementation

[Jun'ichi Nomura]

This patch implements 'anywhere' policy.

o relax_allocation_requests() is added to split the allocation requests
  into smallest possible pieces so that they can fit into any number of PVs.

o _setup_alloced_segment() needed to be changed because it assumed
  the list items in ah->alloced_areas[0] can be used as array.
  It's no longer true.

o dm_pool_free() in relax_allocation_requests() seems to free whole
  alloc_handle and not usable. I might be using it in wrong way.
