Hi Jason,

One addition, there is an issue (I would call it a bug) in random.c before 4.8
where the nonblocking_pool is not reseeded during early boot even though
entropy may be available. That issue aggravates early boot time entropy issues
for user and kernel land.
I have not heard about accepting or rejecting it, so I am wondering how
patches go into random.c at all.
