31 /* One for each parameter, describing how to use it.  Some files do
41  * NOARG - the parameter allows for no argument (foo instead of foo=1)
61  * UNSAFE - the parameter is dangerous and setting it will taint the kernel
102  * module_param - typesafe helper for a module/cmdline parameter
103  * @name: the variable to alter, and exposed parameter name.
104  * @type: the type of the parameter
107  * @name becomes the module parameter, or (prefixed by KBUILD_MODNAME and a
108  * ".") the kernel commandline parameter.  Note that - is changed to _, so
