These get allocated and freed millions of times on this kernel tree. Use a dedicated kmem_cache pool and avoid costly dynamic memory allocations. Most allocations' size is: (sizeof(struct dma_buf) + sizeof(struct reservation_object)). Put those under kmem_cache pool and distinguish them with dmabuf->from_kmem flag.
