2.2.x: Secret stack size limit in Driver file-ops??? (Was:are Generic ioctls a good thing?)

Hi kernel hackers, Is there a limit to the stack size (automatic variables) in driver methods, esp. ioctl? I was just implementing some generic ioctls where the size field and cmd field are defined at runtime. For testing I use a kernbuf on the stack. The driver's ioctl interface, which is
