Discussion in the thread: http://patches.dpdk.org/patch/71351/ Because one of bug fix patch in the patch needed to be backported, and it w= as hard to use rte_atomic* API to do the fix, so C11 atomic built-in was used.= To keep code in stable release clean, decision was made to backport all other patches in the patch= set that involves C11 atomic built-in. >=20 >=20
