Google Android Gingerbread Is Using EXT4

It's very simple.
When using raw flash access, they use YAFFS (they use it on the Nexus S too!!)
When using flash that has a disk emulation layer, like the Samsung's oneNand/mNand, then they use EXT4, because YAFFS doesn't work on that, and wear leveling is already implemented at the emulation layer.
That's what the Nexus S also uses, and the Galaxy S uses (the SGS only uses that in fact, the Nexus S has a YAFFS part and a EXT4 part)
They're both just fine and using EXT4 on top isnt especially always faster or slower than YAFFS, it depends on the chip implementation too.

can only edit post for 1min and phoronixwent down for 2 min when i edited lol..
Anyway http://project-voodoo.org/ to make ur SGS use EXT4, its not a bad hardware memory issue but a software bug. Also XXJPU firmware fixes it (but its a beta)

What's the benefit for Phones?
Journalled file systems on a flash device make no sense.
Most Android phones run in memory anyhow, 512MB if you're lucky to have a phone with that much space in memory.
2-16GB file systems are better off with Fat32. Due to copywrite problems they possibly be better off with ext2.
1. barrier=0 or barrier=1 ?
2. Does Android write data to the file system like Tso says it should?
3. fsck.ext4 included in the tools?
* When will we get a proper task-killer from G0ogle?

Now if only the drivers where more modular:
"and updated OpenGL ES graphics drivers"
Tying drivers with OS upgrades is dumb people.
(I know updated base drivers is good.
But the thing is that this is a sign of drivers being bound to certani OS upgrades.)
