Crashing soon a kernel near you

This is a list of some of the ongoing patches being developed at the kernel community that will be part of future Linux releases. Those features may take many months to get into the Linus' git tree, or may be dropped. The features are tested in the -mm tree, but be warned, it can crash your machine, eat your data (unlikely but not impossible) or kidnap your family (just because it has never happened it doesn't mean you're safe):

• Con Colivas' RSDL process scheduler, which seems to work much better than the stock scheduler according to some reports [http://lwn.net/Articles/224865/ (LWN article)]

• For too long the linux wireless support hasn't been as bright as it should, specially from a desktop-ready POV. A new wireless stack based on the GPLed Devicescape wifi stack has been being developed for many time and soon will be merged. It brings better hardware support, better wireless capabilities, and better tool enablement.
