[KERNEL][MOD][CM7] Huexxx's kernel 120321-V4.1 beta ...
This is a custom kernel for Optimus Black based on CM's Sniper kernel source.
It aims to continue with knzo's previous hard work (all credits go to him) but in a progressive way.
The name of the kernel contains two different 'fields':
- The date of the latest original lge-kernel-sniper included commit. You can check at https://github.com/CyanogenMod/lge-kernel-sniper
if my last kernel includes the latest commits. In negative case, post here to ask for a new up to date recompilation.
- Huexxx's version of the kernel.
Use at your own risk.

Q. Do I need to wipe data?
A. No, never.
Q. Do I need to flash this if I flash a new CM update/nightly?
A. Yes. Everytime you flash a new CM version, you need to reflash this.
Q. I have xxxxx ROM. Can I flash this stuff?
A. This kernel is intended to flash it over CM7 ROMs. It won't work over stock ROMs.
Q. What can we expect from this?
A. Snappier, increased internet/market page loading, USB transfer rate, etc.
Q. How can I know if I flashed it correctly?
A. Go to About Phone in settings and you should see my nick around there.
Q. How can I change governor and set it on boot?
A. Go to Settings > CyanogenMod settings > performance > CPU Settings.
Q. How can I change I/O scheduler?
A. Don't change it for now... default one is Deadline and it works very well.
Q. What governor and/or scheduler is the best?
A. Take a look at this amazing post from knzo. IMHO Smartass V2 (more performance) and InteractiveX (more battery saving) are the best. It seems that new Lazy governor is working so good at Nexus S community, so you can give it a try and comment.
Q. Where can I find the source for this?
--> It's under construction right now...
