I just replied to Andrew. It's not an RT feature per se.
And yes Peter CC'ed RT folks. You probably did not get a chance to read all replies.
They had some questions/concerns and stuff. I believe I answered/clarified all of them.
No hurry I guess. I did mentioned in the introductory email that I've been maintaining
this stuff for awhile now. SLAB patches used to be messy, with new SLUB the mess goes away.
CFS handles CPU hotplug much better than O(1), cpu hotplug is needed to be able to change
isolated bit from sysfs. That's why I think it's a good time to merge.
I don't mind of course if we put this stuff in -mm first. Although first part of the patchset
(ie exporting isolated map, sysfs interface, etc) seem very simple and totally not controversial.
Stop machine patch is really the only thing that may look suspicious.
