FSTRIM support in MIUI

[sweiss33]

Hi all,
I'm using miui on an SGS2, which is based on Android 4.1.2.
I know that in Android 4.3 there's fstrim support, and I was wondering if there's a way of getting that on 4.1,by maybe using a custom kernel or so, while still keeping miui.

Is it possible?

It seems to be incompatible with SGS2,won't let me install :-/
Is there another way? Even something less user friendly?
