Recently Martin Kepplinger reported a problem with the SCSI runtime PM
code. Alan Stern root-caused the reported deadlock. This patch series is
an attempt to fix that deadlock. These patches compile but have not yet
been tested.
Bart Van Assche (6):
ide: Do not set the RQF_PREEMPT flag for sense requests
scsi: Remove an incorrect comment
scsi: Pass a request queue pointer to __scsi_execute()
scsi_transport_spi: Make spi_execute() accept a request queue pointer
scsi_transport_spi: Freeze request queues instead of quiescing
block, scsi, ide: Only submit power management requests in state
