	select BLK_SCSI_REQUEST
	---help---
	  If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
	  any other SCSI device under Linux, say Y and make sure that you know
	  the name of your SCSI host adapter (the card inside your computer
	  that "speaks" the SCSI protocol, also called SCSI controller),
	  because you will be asked for it.

	  You also need to say Y here if you have a device which speaks
	  the SCSI protocol.  Examples of this include the parallel port
	  version of the IOMEGA ZIP drive, USB storage devices, Fibre
	  Channel, and FireWire storage.

	  To compile this driver as a module, choose M here and read
	  <file:Documentation/scsi/scsi.txt>.
	  The module will be called scsi_mod.

	  However, do not compile this as a module if your root file system
	  (the one containing the directory /) is located on a SCSI device.

config SCSI_MQ_DEFAULT
	bool "SCSI: use blk-mq I/O path by default"
	depends on SCSI
	---help---
	  This option enables the new blk-mq based I/O path for SCSI
	  devices by default.  With the option the scsi_mod.use_blk_mq
	  module/boot option defaults to Y, without it to N, but it can
	  still be overridden either way.

	  If unsure say N.

config SCSI_PROC_FS
	bool "legacy /proc/scsi/ support"
	depends on SCSI && PROC_FS
	default y
	---help---
	  This option enables support for the various files in
	  /proc/scsi.  In Linux 2.6 this has been superseded by
	  files in sysfs but many legacy applications rely on this.

	  If unsure say Y.

config BLK_DEV_SD
	tristate "SCSI disk support"
	depends on SCSI
	---help---
	  If you want to use SCSI hard disks, Fibre Channel disks,
	  Serial ATA (SATA) or Parallel ATA (PATA) hard disks,
	  USB storage or the SCSI or parallel port version of
	  the IOMEGA ZIP drive, say Y and read the SCSI-HOWTO,
	  the Disk-HOWTO and the Multi-Disk-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>. This is NOT for SCSI
	  CD-ROMs.

	  To compile this driver as a module, choose M here and read
	  <file:Documentation/scsi/scsi.txt>.
	  The module will be called sd_mod.

	  Do not compile this driver as a module if your root file system
	  (the one containing the directory /) is located on a SCSI disk.
	  In this case, do not compile the driver for your SCSI host adapter
	  (below) as a module either.

config CHR_DEV_ST
	tristate "SCSI tape support"
	depends on SCSI
	---help---
	  If you want to use a SCSI tape drive under Linux, say Y and read the
	  SCSI-HOWTO, available from
	  <http://www.tldp.org/docs.html#howto>, and
	  <file:Documentation/scsi/st.txt> in the kernel source.  This is NOT
	  for SCSI CD-ROMs.

	  To compile this driver as a module, choose M here and read
	  <file:Documentation/scsi/scsi.txt>. The module will be called st.

config CHR_DEV_OSST
	tristate "SCSI OnStream SC-x0 tape support"
	depends on SCSI
	---help---
	  The OnStream SC-x0 SCSI tape drives cannot be driven by the
	  standard st driver, but instead need this special osst driver and
	  use the  /dev/osstX char device nodes (major 206).  Via usb-storage,
	  you may be able to drive the USB-x0 and DI-x0 drives as well.
	  Note that there is also a second generation of OnStream
	  tape drives (ADR-x0) that supports the standard SCSI-2 commands for
	  tapes (QIC-157) and can be driven by the standard driver st.
	  For more information, you may have a look at the SCSI-HOWTO
	  <http://www.tldp.org/docs.html#howto>  and
	  <file:Documentation/scsi/osst.txt>  in the kernel source.
	  More info on the OnStream driver may be found on
	  <http://sourceforge.net/projects/osst/>
	  Please also have a look at the standard st docu, as most of it
	  applies to osst as well.
