Looks good to me, but you may also want to link to the proposed wording for
mandating SEEK_HOLE/SEEK_DATA in the eventual POSIX Issue 8 (POSIX 2008 is
Issue 7):
http://austingroupbugs.net/view.php?id=415

Also, it seems a shame that the kernel can fail with EINVAL instead of
properly emulating SEEK_HOLE and SEEK_DATA even on file systems with no
underlying support for reporting holes.

Thanks for catching that. I've added that point.

Cheers,

Michael
