-rc4, as of this writing. They are fixes, mostly in the architecture,
ALSA, and networking subsystems.
The current -mm tree is 2.6.20-rc3-mm1. Recent changes
to -mm include a bunch of KVM work (see below), another set of workqueue
API changes, and the virtualization of struct user.
The current stable 2.6 kernel is 184.108.40.206, released on January 10. It
