F2FS support

While this kernel (from a22 on) includes the f2fs driver, it does not include any of the ramdisk or init tweaks that you would need to use f2fs. This is because I am not in a position to test f2fs myself. That said, the a22 (and later) kernel installer will not disturb any changes you have already made to your ramdisk or ROM to support f2fs, so if you have already got f2fs working on your device, it should continue to work after installing this kernel. Don't forget to do a nand backup in your recovery before installing, though. Seriously.

NTFS R/W support

This kernel (from a22 on) includes RW support for NTFS. However, in KitKat, NTFS USB drives mounted with StickMount are not writable due to SELinux policy. To write to an NTFS USB drive, you need to (from a root shell) 'setenforce off', then 'setenforce on' when you're done using it. I do not recommend that you put SELinux in permissive mode permanently. It's there for a reason, and this is just a workaround for a policy error in KitKat. The SELinux SetEnforce Toggle app is a convenient way to turn it off and on for this.

Camilla: You, sir, should unmask.
Stranger: Indeed?
Cassilda: Indeed, it's time. We all have laid aside disguise but you.
Stranger: I wear no mask.
Camilla: (Terrified, aside to Cassilda) No mask? No mask!
