The kernel has always done a certain amount of "default policy".

What do you think things like "swappiness" etc are? Or things like oevrcommit settings? They're all policies, and there is always a default one. So in that sense the kernel always has - and fundamentally _must_ - set some kind of policy.

And the default policy should generally be the one that makes sense for most people. Quite frankly, if it's an issue where all normal distros would basically be expected to set a value, then that value should _be_ the default policy, and none of the normal distros should ever need to worry.

Whether this case is one such, I dunno. Quite frankly, I don't think it's even _nearly_ important enough to get this kind of noise.

More and more are wanting and now finding the Linux kernel to be more
RT capable. I seem to remember way back you saying it was one thing you didn't really care much about one way or the other. Thats OK. But, you _are_ the man. Put an end to this. Are you going to allow the long
understood meaning of SCHED_FIFO to change in the Linux kernel just to protect a few _supposedly_ bad programmers???
