One of the features of the file system Ext4 is its new Scalability features documented here. I was wondering what changes at the source code level would enable Ext4 to support such features, like the virtually unlimited number of sub directories which Ext3 didn't. Pointers to the relevant areas of the Kernel source tree would be greatly ...
