--- Comment #3 from Pedro F. Giffuni <pfg@FreeBSD.org> ---
Off the top of my head ...

We do have some support for sparse files, based on the generic
support for UFS:

https://svnweb.freebsd.org/base/head/sys/fs/ext2fs/ext2_vnops.c?r1=3D252956=
&r2=3D252955&pathrev=3D252956

I don't think we have any filesystem-specific code to deal
with it (which would be ideal).
