168 * otherwise bad things will happen (hashbins will be NULL for example).
169 * Those modules are at module_init()/device_initcall() level.
171 * On the other hand, it needs to be initialised *after* the basic
172 * networking, the /proc/net filesystem and sysctl module. Those are
173 * currently initialised in .../init/main.c (before initcalls).
174 * Also, IrDA drivers needs to be initialised *after* the random number
175 * generator (main stack and higher layer init don't need it anymore).
