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);

ARGUMENTS
       sdev
	   device to resume

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 (which must be a legal transition) allowing the midlayer to goose the queue
       for this device. This routine assumes the host_lock is held upon entry.
