Jens,

Any objections to me picking this up?

> The SCSI runtime suspend and SPI domain validation mechanisms both use
> scsi_device_quiesce(). scsi_device_quiesce() restricts
> blk_queue_enter() to BLK_MQ_REQ_PREEMPT requests. There is a conflict
> between the requirements of runtime suspend and SCSI domain
> validation: no requests must be sent to runtime suspended devices that
> are in the state RPM_SUSPENDED while BLK_MQ_REQ_PREEMPT requests must
> be processed during SCSI domain validation. This conflict is resolved
> by reworking the SCSI domain validation implementation.

> Hybernation, runtime suspend and SCSI domain validation have been
> retested.
