Nuta: Exploring the internals of Linux v0.01

For those who find the 6.x kernel intimidating, Seiya Nuta has written a look at the 0.01kernel, which reflects a simpler time.

By the way, there's an interesting comment about the scheduler:

 * 'schedule()' is the scheduler function. This is GOOD CODE! There * probably won't be any reason to change this, as it should work well * in all circumstances (ie gives IO-bound processes good response etc).

Yes it's indeed good code. Unfortunately (or fortunately), thisprophecy is false. Linux became one of most practical andperformant kernel which has introduced many new schedulingimprovements and algorithms over the years, like Completely FairScheduler (CFS).
