"The min_granularity setting was renamed to base_slice in this commit in v6 kernel.

The comment says it scales with CPU count and the comment is incorrect. I wonder whether kernel developers are aware of that mistake as they are rewriting the scheduler!

  • Official comments in the code says it’s scaling with log2(1+cores) but it doesn’t.
  • All the comments in the code are incorrect.
  • Official documentation and man pages are incorrect.
  • Every blog article, stack overflow answer and guide ever published about the scheduler is incorrect."

    Yeah I was wondering this too - is 8 the floor, 8 cores or below the value is always the same, but above 8 cores you then get your log progression? I don't know enough about this though.
