   4See Documentation/kernel-parameters.txt for general information on
   5specifying module parameters.

   7This document may not be entirely up to date and comprehensive. The command
   8"modinfo -p ${modulename}" shows a current list of all parameters of a loadable
   9module. Loadable modules, after being loaded into the running kernel, also
  10reveal their parameters in /sys/module/${modulename}/parameters/. Some of these
  11parameters may be changed at runtime by the command
  12"echo -n ${value} > /sys/module/${modulename}/parameters/${parm}".
