1	                          SCSI Kernel Parameters
2	                          ~~~~~~~~~~~~~~~~~~~~~~
3	
4	See Documentation/kernel-parameters.txt for general information on
5	specifying module parameters.
6	
7	This document may not be entirely up to date and comprehensive. The command
8	"modinfo -p ${modulename}" shows a current list of all parameters of a loadable
9	module. Loadable modules, after being loaded into the running kernel, also
10	reveal their parameters in /sys/module/${modulename}/parameters/. Some of these
11	parameters may be changed at runtime by the command
12	"echo -n ${value} > /sys/module/${modulename}/parameters/${parm}".
