As of Kernel 4.8, Ted Ts'o has already switched /dev/urandom over to ChaCha20 (https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=818e607b57c94ade9824dad63a96c2ea6b21baf3 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux....), so I would say a good CSPRNG's already done.
