Please note, the use of the ktime_get_raw_ns() is *only* used as a fallback on architectures where random_get_entropy / get_cycles is not implemented.
So, on X86 and on many other arches, this function call will never be triggered.

Will do.
@Arnd: I would prepare a patch then using ktime_get_raw_ns and providing a good documentation in the code.
Ciao Stephan
