+======================
+SCSI Kernel Parameters
+======================
+
+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}``.
