    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):

    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.
