Motorola has uploaded kernel source files for the DROID Turbo 2 (Kinzie) to GitHub. Here developers and tinkerers alike can download the code and dive inside to get a look at what makes Android 6.0 work on the device.
General users won't benefit from downloading the files directly themselves. They may, however, gain something from developers who use this code to improve their apps. This access also increases the likelihood of seeing custom ROMs.
In short, if you don't know what these files are, they're of no use to you. But if you've been waiting to get your hands on them, have at the source link below.
