Why 16? Please make is MAX_SG + 1 this makes some sense.
Wouldn't MAX_SG mean

Wouldn't MAX_SG mean we always allocate from the cache? Isn't the memory waste
too big in this case?

Currently if VIRTIO_RING_F_INDIRECT_DESC is enabled we will
use indirect descriptors and allocate them using a simple
kmalloc().
This patch adds a cache which will allow indirect buffers under
a configurable size to be allocated from that cache instead.
