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