Finally the day come that Android merges back to Linux repositories. Android Kernel was forked from Linux but failed to merge back due to disagreement between developers from both projects. With the latest news from lwn.net and kernelnewbies.org it has been stated that various Android subsystems and features have already been merged, and more will follow in the future.
Android has taken linux somewhere no linux fan could ever imagine, today even Microsoft is building applications for Android which actually made them built applications for linux. Avery good news for both parties for the future of both projects.
