Shouldn't it be 8 for older kernels?
Looking into source code I would say Linux 5.17 requires 64 bytes to
init crng.
8 bytes rng_seed should help somehow, but It will not init crng
instantly.
Maybe some even Linux required only 8 bytes but I doubt so.
8 bytes was too small for cryptographic PRNG yet 20 years ago.
To sum up the replies from Marek, the lower limit should be 64.

Perhaps this would read better:
"Value for rng_seed_size too low (%lu) and likely insufficient
for the Linux RNG initialization"
Thanks, I will apply It in v3.
Great, thanks!
