See Documentation/admin-guide/kernel-parameters.rst for general information on
specifying module parameters.

This document may not be entirely up to date and comprehensive. The command
"modinfo -p ${modulename}" shows a current list of all parameters of a loadable
module. Loadable modules, after being loaded into the running kernel, also
reveal their parameters in /sys/module/${modulename}/parameters/. Some of these
parameters may be changed at runtime by the command
"echo -n ${value} > /sys/module/${modulename}/parameters/${parm}".

			See drivers/scsi/mac_scsi.c.

	scsi_mod.max_luns=
			[SCSI] Maximum number of LUNs to probe.
			Should be between 1 and 2^32-1.

	scsi_mod.max_report_luns=
			[SCSI] Maximum number of LUNs received.
			Should be between 1 and 16384.

	NCR_D700=	[HW,SCSI]
			See header of drivers/scsi/NCR_D700.c.

	ncr5380=	[HW,SCSI]
			See Documentation/scsi/g_NCR5380.txt.

			See Documentation/scsi/g_NCR5380.txt.

			See Documentation/scsi/g_NCR5380.txt.

	ncr53c8xx=	[HW,SCSI]

	osst=		[HW,SCSI] SCSI Tape Driver
			Format: <buffer_size>,<write_threshold>
			See also Documentation/scsi/st.txt.

	scsi_debug_*=	[SCSI]
			See drivers/scsi/scsi_debug.c.

	scsi_mod.default_dev_flags=
			[SCSI] SCSI default device flags
			Format: <integer>

	scsi_mod.dev_flags=
			[SCSI] Black/white list entry for vendor and model
			Format: <vendor>:<model>:<flags>

	scsi_mod.scsi_logging_level=
			[SCSI] a bit mask of logging levels
			See drivers/scsi/scsi_logging.h for bits.  Also
			settable via sysctl at dev.scsi.logging_level
			(/proc/sys/dev/scsi/logging_level).
			There is also a nice 'scsi_logging_level' script in the
			S390-tools package, available for download at
			http://www-128.ibm.com/developerworks/linux/linux390/s390-tools-1.5.4.html

	scsi_mod.scan=	[SCSI] sync (default) scans SCSI busses as they are
			discovered.  async scans them in kernel threads,
			allowing boot to proceed.  none ignores them, expecting
			user space to do the scan.
