SCSI_INTERNAL_DEVICE(9)                   SCSI mid layer                  SCSI_INTERNAL_DEVICE(9)



NAME
       scsi_internal_device_unblock - resume a device after a block request

SYNOPSIS
       int scsi_internal_device_unblock(struct scsi_device * sdev,
                                        enum scsi_device_state new_state);

ARGUMENTS
       sdev
           device to resume

       new_state
           state to set devices to after unblocking

DESCRIPTION
       Called by scsi lld's or the midlayer to restart the device queue for the previously
       suspended scsi device. Called from interrupt or normal process context.

       Returns zero if successful or error if not.

NOTES
       This routine transitions the device to the SDEV_RUNNING state or to one of the offline
       states (which must be a legal transition) allowing the midlayer to goose the queue for
       this device.
