I don't think we can include stdint.h here, the entire point of the custom kernel types is to ensure the other kernel headers can use these types without relying on libc headers. While some of driver specific kernel headers have libc dependencies in them, the general rule is to keep the kernel headers as standalone usable. Arnd
