Next up we have ourselves a test build for the hwa enabled roms. This one was/is a feature testing build for improvements to zram and inclusion of zcache and related items. No one has this kernel until now. This kernel is probably the most unstable kernel I have ever released, it's really rough, but was built to test the zcache feature and not much else, stability of everything wasn't a concern. You might find that is also has some other changes including xz decompression as well as some improvements to the vr and sio schedulers. It's closer feature wise to the release of 15, but has some very experimental features enabled so your mileage will very. Don't complain if it eats your soul or does horrible things, as it's a tester, not meant for mass adoption, hell it might not even boot at all. How do you turn zram on in the first place you ask? These are the commands you need with superuser privileges in either a terminal emulator or adb shell.
If you don't know how to put those in, you probably shouldn't be messing with it. That is all.
