Hi Joel,
are there any plans to submit an e2fsprogs patch to print out the
"shared" extent flag from "filefrag"?
At first glance it would also seem to make sense to set this flag for
ext2/3/4 xattrs that are sharing an external extent block.
Cheers, Andreas

Yes, I do have a patch for filefrag which I will push after this
gets into mainline.
