ioctls are used to provide non-standard services for UNIX device
drivers. These are things that don't fit into the usual
open/close/read/write/seek model. You can use ioctl for user->kernel
communication. You shouldn't use it directly for user->rt-modules.
You can't normally use it for kernel->user communications.
