Since the two functions
prandom_byte_state and prandom_u32_state
use the weak prng prandom_u32,
we added the prefix predictable_rng,
to their signatures so it is clear they are weak.
It's fancy indentation.

/* Fisher-Yates shuffle */
for (i = count - 1; i > 0; i--) {
- rand = prandom_u32_state(&state.rnd_state);
+ rand = predictable_rng_prandom_u32_state(&state.rnd_state);
Isn't it too many "random":s encoded in the name?
I would leave either "rng" or "[p]random".
rand %= (i + 1);
swap_free_obj(slab, i, rand);
}
