It seems no serious kernel developer cares enough to get to it. It's just a desktop feature you know - no big iron - uninteresting. >> Why keep it in -mm for so long? >> > > I'm waiting to be shown that its benefits exceed its costs.

I imagine it must be really hard to fight to something you don't even exists. Or prove that you are better than somebody you have never seen or heard of. Please somebody qualified, take the time, dig that code, and show us those costs. With details. So Con can make the code even better and included in mainline or drop altogether if it's really bad and move on to other endeavours.
