I don't know the typical uses (or the code at all). But it might be worth having a small array in the structure itself. Useful if there are typically always (say) less than 8 buffers. For larger sizes use the (IIRC) kmalloc_size() to find the actual size of the structure that will be allocate and set the array size appropriately.
