ib_alloc_device - allocate an IB device struct :size of structure to allocate
Low-level drivers should use ib_alloc_device() to allocate &struct ib_device. is the size of the structure to be allocated, including any private data used by the low-level driver. ib_dealloc_device() must be used to free structures allocated with ib_alloc_device().

ib_alloc_fast_reg_page_list - Allocates a page list array - ib device pointer. - size of the page list array to be allocated.
This allocates and returns a struct ib_fast_reg_page_list * and a page_list array that is at least page_list_len in size. The actual size is returned in max_page_list_len. The caller is responsible for initializing the contents of the page_list array before posting a send work request with the IB_WC_FAST_REG_MR opcode.
The page_list array entries must be translated using one of the ib_dma_*() functions just like the addresses passed to ib_map_phys_fmr(). Once the ib_post_send() is issued, the struct ib_fast_reg_page_list must not be modified by the caller until the IB_WC_FAST_REG_MR work request completes.
