It has been requested that the NVMe fault injector be able to inject faults when accessing

Curious, but who has requested this?  Because injecting errors really
isn't the drivers job.

It's an application (database) that is requesting it for their error
handling testing.
Well, how about they then insert it into the real or virtual hardware.
The Linux nvme driver isn't really an error injection framework.

Sorry if you receive multiple of these, I'm having email/sending issues.


I get it, but there is already an injection framework in place for nvme. Is there no plan to improve it?
