Subject: nvme/{016,017}: Make the number iterations configurable
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=b79ba018a0feb89cba4711a7892a6cdd85e37e02;p=users%2Fsagi%2Fblktests.git

nvme/{016,017}: Make the number iterations configurable

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.
