[PATCH blktests v3 12/12] nvme: Make the number iterations configurable

Daniel Wagner
2023-05-03T08:04:18Z

Some tests hard code high values of iterations. This makes them run
relatively long compared to the other tests. Introduce a new environment
variable nvme_num_iter to allow tune the runtime.
