I'm currently evaluating the ext4 allocator and one thing I've come across is the lack of a tool that displays the exact structure of the extents making up a file. I've found plenty of tools that will tell me how many contiguous segments a file contains, but nothing so far to let me see the actual makeup of the extents that map the inode to the blocks that comprise the file. Have I just missed something obvious, or would this be something worth me spending some time doing? If so, one option would be to either modify the stat command or add a similar command in debugfs to show the extents from the roots through the root down to the leafs. Anyone have preferences or opinions?
