Subject: [PATCH blktests v4 05/11] nvme{032,040}: Use runtime fio background jobs

The fio jobs are supposed to run long in background during the test.
Instead relying on a job size use explicit runtime for this.

Is there any issue with the exiting approach for this change ?

The expectation of the test here is that there is a background job running.
Depending on the job size is an indirect way to express run at least for x
seconds. This gives a variable runtime as it depends the how fast fio jobs gets
executed. Explicitly telling the runtime is my opinion more robust and documents
the indention better.

agree, it is better to kill on rely on the variable while test is
running ...
