I am not sure I understand your reply. The offered patch set does not rip out
existing code. It adds a replacement implementation which can be enabled
during compile time. Yet it is even disabled per default (and thus the legacy
code is compiled).
I see such a development approach in numerous different kernel core areas:
memory allocators (SLAB, SLOB, SLUB), process schedulers, IRQ schedulers.
What is so different for the realm of RNGs?
Ciao
Stephan
