Why removing REQ_FAILFAST_DRIVER in LightNVM?

[Javier González <jg@xxxxxxxxxxx>]

Hi Christoph,

I'm cleaning up lightnvm.c to use as much as possible the nvme helpers.

I see that in Commit: d49187e97e94 "nvme: introduce struct nvme_request"

you introduced:
  rq->cmd_flags &= ~REQ_FAILFAST_DRIVER

on the lightnvm I/O path and that has propagated through the code as we
added more functionality. Can you explain why this is necessary? If I
can just remove it, it is much easier to do the cleanup.

I have tested on or HW and all works fine without it.

Thanks,
Javier
