Discussing things doesn't usually work well.  Let's see some working
patches first, that solve problems that you have with the current random
code, and we can go from there.

Again, like any other kernel patch submission, nothing new here at all.

If everyone seems to think their patches are hacks, and are not worthy
of being submitted, then why do they think that somehow they are viable
for their users that are actually using them?

{sigh}
