Sedat> What's the plan... s/pr_warn/pr_debug ?

The rationale here is that we'd like to log (once) if discard or write
same fail on a given device.

In SCSI we disable these commands if they get failed by the storage. But
it looks like loop keeps advertising discard support after a failure.

Is your loop device encrypted? Do you know why the discard is failing?
