So far cache operations are only applied on the submission queue and completion queue, but they are missing in other places like identify and block read/write routines. In order to correctly operate on the caches, the DMA buffer passed to identify routine must be allocated properly on the stack with the existing macro ALLOC_CACHE_ALIGN_BUFFER().
