If you want to do it simpler and safer use strnlen.
Also, don't mix -1 wit -errno returns.
size_t len = strnlen(ops_name, RTE_MEMPOOL_OPS_NAMESIZE);
if (len == 0)
return -EINVAL;
if (len == RTE_MEMPOOL_OPS_NAMESIZE)
return -ENAMETOOLONG;

No need to Cc stable in my opinion, as there is no bug fixed.
Changing the name to:
mbuf: prevent setting mempool ops name empty
Applied with below minor change, thanks
The blank line below should remain:
