Well, I'm writing a packet defragmenting code. I have a data structure
consisting of a rte_hash, a rte_ring and an array allocated with
rte_zmalloc. All these besides the ring can be freed. So looks like I
can't destruct my object after allocating. Strictly speaking, I don't
have to. The need shouldn't arise in normal situation. I just considered
writing allocating/deallocating function pairs and processing all
allocation errors to be a good practice.
Isn't it a bit strange to have rte_hash_free() and not have
rte_ring_free()? What's the reason for this?
Best wishes,
Dmitry
