Subject: How to disable group scheduler correctly?

Hello,

Could anyone tell me which options to enable/disable to have the scheduler behavior as it was before 2.6.25 (i.e, completely disable the group scheduler)? There seems to be a lot of confusion [1] about which options to set or not set, so it would be nice if anyone could give the exact ones.

Thanks.

[1] For example, in Arch Linux the group scheduler was first enabled in 2.6.25, but due to latency issues it was quickly disabled. But after that, the following report claims to have problems with everything *GROUP* disabled and that you need to enable CGROUPS to solve them (the report links to similar reports on Gentoo and Ubuntu, so it seems the confusion is quite general):
