other: ext4 support in kernel #88

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago

Please add Ext4 support in kernel (only need to enable it in kernel like 
ext2/3), its much faster than ext3, and more stable than ext2.

And then what about android part? Only Android 2.3 support ext4. Am I wrong?

cool, what did you change or add in the kernel?
how much performance increase? or is it pure for more stability?

So did you just format as ext4 and that was it? I am very keen ext3 was too 
slow for me and ext2 seems not so stable. Running my storage.

Excuse me, how did you get Android running in a ext4? Because Android don't 
support a ext4 partition!

android don't care about the underlaying filesystem - it's just the kernel who 
must support ext4. you can compile the kenel yourself with ext4-fs than  format 
your partition ext4 and voila.

You can enable the ext4 file system support in the kernel, kernel 2.6.31 
support ext4 out of the box.
