Hi,

Following the findings I presented a few months ago
(http://lkml.org/lkml/2010/4/18/13) about CFS having large vruntime spread
issues, Peter Zijlstra and I pursued the discussion and the implementation
effort (my work on this is funded by Nokia

I think you got that backwards. The patches intent to make the desktop LESS responsive.

Read the original thread and the response from Torvalds:

yeah, that was the case with the old patches & thread from April

but the new says:

The
Xorg interactivity is very good with the new features enabled, but was poor
originally with the vanilla mainline scheduler.

I haven't noticed any adverse effects yet, let's see how good those patches really are in everyday work and heavy load, webradio streaming, etc.

Gleixner's comments aren't too promising though, lol.

I wish they would put BFS in the kernel and be done with it anyway.
