I'm changing the current hpa_get_freespace based on this current need
from pmem and some issues reported by Gregory regarding concurrency when
several drivers try to get things done. The current implementation
reports max free space and the allocation is done later on what with
those concurrency issues seems to not be the right solution.
I will post a new version early next week.
