As many people where demanding a Ext4 Kernel I created one and added a Filesystem conversion script.

This does only work on Gingerbread ROMs cause the bootloader is different!
On Froyo it will cause the device not to boot into the normal android system. Don't flash it if you are not on a Gingerbread ROM.
I have tested it with KPH but it should work on all Gingbread ROMs that have a updated bootloader.

FS converter? WTF???
This converts (formats) all your internal partitions (system, data, cache) with Ext4.
This way you don't have to use RFS which performance is pretty poor.

How to install?

1. Install CWM (there some threads here how to do this)
2. Make a Nandroid backup of your system (this is essential otherwise all your data will be lost!!!)
3. Install the ext4-update.zip (this will format your partition into EXT4 and flash a new Kernel)
4. Go into "mounts and storage" -> unmount cache (if it is mounted)
5. Go to "backup and restore" -> "advanced restore"
6. Choose the backup you made before -> Restore System & Data (cache is not needed it is rebuild on the next reboot)
7. Reboot
8. Don't panic (it will take some time to rebuild the dalvik cache,
   just like the first boot after you flashed a new rom with ODIN)

Follow those instructions otherwise all your data will be lost and i make fun of you!

This will install a Kernel that has EXT4 support and a modified init.rc to mount both ext4 and rfs partitions.

Ok enough talked, where can I get this ****? Here MD5: 369808990ff8d45065f0cdd8fbb3f8b8

WTH you bricked my Phone
This is impossible. Except your CWM is buggy. You phone doesn't boot up, you are stucked at the samsung logo?
Ok then we need some information from you. Did you hear the start-up sound the the samsung logo player?
How long did you wait?
Try to adb to the phone and give me the output from "mount" and "logcat" on pastebin.com pls.
Please tell us witch rom you were running. I am not sure if this will work with any custom rom cause i only tested stock
You can fully revert by flashing a Full ROM with ODIN. Then install cwm and restore the backup you created before.


How did you create this?
I simply build the kernel source added Ext4 support. Kernel source is on github
Then I created a new initramfs by dumping the stock one doing the modifications and repacking it. The Initramfs is also on github. This should help anyone of you trying to the some on your custom kernel.

Cool dude ....
Is this a OC kernel ?>???
Nice work dude for this 1 ....
Appreciate ur work

Great work...
Getting ext4 support means it will format the sd card fully or just creates a partition with the free memory left in the sd card?

nope nothing touched except FS support. I think i won't add anything like that cause it want to save my time to work on CyanogenMod. But everyone feel free to modify the source and do it :)

Are you working on CM for ACE? Thx for kernel, nice work. )

There is no RFS filesystem's source in your source, how do you compile a kernel supporting RFS?

samsung just give we modules for rfs support.
it included in boot.img

what are the advantages of using EXT4 as filesystem?
