Clear message


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.

Release Note


Not every patch and/or driver carried in the Ubuntu delta is automatically sync'd with the upstream kernel for various reasons. This places a maintenance burden on the Ubuntu kernel team. These patches and/or drivers must be regularly reviewed to determine if they are still needed, if they need updating to a later version, or if they are now ready for upstream acceptance. The purpose of this blueprint is to facilitate and record this review for the 13.04 cycle.
