The async vhost callback ops should return negative value when there are something wrong in the callback, so the return type should be changed into int32_t. The issue in vhost example is also fixed. Fixes:cd6760da10("vhost: introduce async enqueue for split ring") Fixes:819a716858("vhost: fix async callback return type") Fixes:6b3c81db8b("vhost: simplify async copy completion") Fixes:abec60e711("examples/vhost: support vhost async data path") Fixes:6e9a9d2a02("examples/vhost: fix ioat dependency") Fixes:873e8dad6f("vhost: support packed ring in async datapath") Cc: stable@dpdk.org Signed-off-by: Cheng Jiang <cheng1.jiang@intel.com> Reviewed-by: Maxime Coquelin <maxime.coquelin@redhat.com>
