Re: [PATCH v4 0/9] Rework runtime suspend and SPI domain validation

Bart,

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.

Applied to 5.11/scsi-staging except for patch #5. Appreciate all that
work that went into this series!
