v1->v2
- Change title to more descriptive one
- Add issue reproduce information to git log body
On current master tree, normal DPDK make will result in
the below error:
error: ‘ids[0]’ may be used uninitialized in this
function [-Werror=maybe-uninitialized]
ret = rte_service_map_lcore_set(i, ids[lcore_iter], 1);
It can be reproduced very easily on Fedora 21 with
gcc-4.9.2-6.fc21.x86_64.
It is fixed after applied this patch.
