scsi_activate_tcq - turn on tag command queueing
scsi_add_device - creates new scsi device (lu) instance
scsi_add_host - perform sysfs registration and SCSI bus scan.
scsi_add_timer - (re-)start timer on a SCSI command.
scsi_adjust_queue_depth - change the queue depth on a SCSI device
scsi_assign_lock - replace default host_lock with given lock
scsi_bios_ptable - return copy of block device's partition table
scsi_block_requests - prevent further commands being queued to given host
scsi_deactivate_tcq - turn off tag command queueing
scsi_delete_timer - cancel timer on a SCSI command.
scsi_host_alloc - return a new scsi_host instance whose refcount==1
scsi_host_get - increments Scsi_Host instance's refcount
scsi_host_put - decrements Scsi_Host instance's refcount (free if 0)
