A large part of the problem is that there's none and the semantics
is a hode-podge of random flags that mostly make little sense
outside of fs developers debugging the layout that we created. The
closest to a description is Documentation/filesystems/fiemap.txt
in the kernel tree, but that doesn't document most of the delicate
points.
