                          SCSI Kernel Parameters
                          ~~~~~~~~~~~~~~~~~~~~~~

See Documentation/kernel-parameters.txt 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}".
