Ubuntu Kernel Delta Review

Registered by Leann Ogasawara on 2012-04-20

Review of the current Ubuntu Kernel patch delta from upstream. This session will look at the current delta comprised of both patches to the core and the ubuntu specific drivers. The aim is to record what we are carrying, review the reasons for that component(s) to be carried, and recommend replacements, updates, cleanups, upstreaming etc of those components.
