Change Log 03.31.2015
1. Added F2FS support
2. Created a F2FS convert flashable zip to convert /system to F2FS after your ROM has been flashed (Link above) since the new Lollipop updater will always format back to ext4 despite my best efforts.
3. I have been running F2FS on /system and /cache all day long. Enjoy the awesome!!!!!!!!!!!
4. Just a warning, I have not tested this on AOSP 5.0, ONLY 5.1 so just be careful!!!
