Default sched_autogroup interactivity patch for the desktop

Hi,
I've been reading┬*http://lkml.org/lkml/2010/11/16/402┬*and actually Lennart has put some solid thoughts and arguments there and IMHO it was *somehow* pretty convincing that this should be done at user-space, in conjunction with tools such as systemd, albeit introducing more complexity in form of configuration infrastructure and whatnot.


Having this being done automatically by the kernel looks really easy and yet promising. The downside of it is that it just feels like it's something rigged towards a special class of applications (TTY based, build jobs) and would act┬*behind the scene without user-space knowing (explicitly) about this classification, cgroups being spawned and subtasks associated to them.


Still, It would be nice to have this differentiation in place, being implemented in either forms, since it brings a certain win for the desktop user and developer. I think having a term open for churning code is part (or a possible user-case) of the desktop experience

Let me guess - Canonical already announced (or will do so within the

Being entirely serious, you should have sent this email on the thread
you indicated. Sending it to this list isn't going to really benefit
the discussion that needs to happen.

Thanks!

I'll test it ASAP on my Xeon workstation(s). *

head) in the background.
