| Subject: [PATCH] test: add latency test using posixaio ioengine |
| |
| Make sure that mean(slat) + mean(clat) = mean(total lat). |
| |
| Tests 15 and 16 use the libaio and null ioengines, respectively. Both of |
| those ioengines have commit hooks. Add this new test using the posixaio |
| ioengine which does not have a commit hook so that we can better cover |
| the possible ways that latency is calcualted. |
