Name:ame_vector_create() - allocate & initialize structure for pinned pfns*@nr_frames: number of pfns slots we should reserve* Allocate and initialize struct pinned_pfns to be able to hold @nr_pfns* pfns.
Proto:struct frame_vector *frame_vector_create(unsigned int nr_frames)
Type:struct frame_vector
Parameter:
