The Merit doesn't really have ext4 enabled kernel, does it?
My kernel does. Compiled from source. flash it and see. Also is swap enabled.
My CWM5 has the same kernel. Compiled CWM5 from source. And my own configs.
Only thing that bugs me a bit about the usbmounting (DONE) ADB talking (DONE) CWM5 I made is the REAL BRIGHT screen...lol
Working on another ROM as we speak....BIG announcement soon about it!!!
