Hi.
Is it safe to enable stats on MT safe services?

It seems to me this would have to be an __atomic_add for this code to
produce deterministic results.
I agree. The same goes for the 'calls' field.
The calling function does the locking.

For more information you can look at:
https://github.com/DPDK/dpdk/blob/main/lib/eal/include/rte_service.h#L120
What about the
https://github.com/DPDK/dpdk/blob/main/lib/eal/common/rte_service.c#L404
call (for MT safe services)?
There's no lock held there.
