Per last week's conference call, I've included an update of the e2fsprogs patchset to support extents. It still needs more work before it can be folded into mainline, but I'm including them so that people can see which way I'm headed, and because debugfs has been enhaced to show extents, which can be useful for developers. One concern I still have is the fact that we're exposing a lot of interfaces in libext2fs.so which are very specifically tied to the current 48-bit physical/32-bit logical on-disk extent data structure. If/when we add support for the 64/64-bit extent data structure, and some kind of compressed/bit-packed extent format, those interfaces will have to be extended. Another problem is that while external extent blocks are getting byte swapped, there is no byte swapping going on for the extents stored in the inode. I haven't tried it on a big endian system, such as Power machine, but I'm pretty sure it's going to blow up spectacularly.
