The revert request came at Morten's suggestion. He has comments on the code and technical reasons why he believes that the approach is not the best one as well as some scenarios where possible race conditions can occur.
Morten, what is the latest update in this area. I'm not sure I have followed your discussion with Vincent on the subject.
Just to make it more clear.. There are two reverts now. Please look at the latest tree/branches. Vincent has provided another fixup patch after which he commented we no longer need Mortens fix.
I have reverted that too, for the moment to keep things same as the last release. Can Morten test with latest patches from Vincent (from his branch) ? And provide fixups again ?
Hi,
I tested Vincent's fix ("sched: pack small tasks: fix update packing domain") for the buddy selection some weeks ago and confirmed that it works. So my quick fixes are no longer necessary.
The issues around the reverted "sched: secure access to other CPU statistics" have not yet been resolved. I don't think that we should re-enable it until we are clear about what it is doing.
Morten
