   5 specifying module parameters.

   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}".
