The normal kstat output includes two metadata headers before the actual value:

    $ cat /proc/spl/kstat/zfs/foo
    31 0 0x01 1 0 1336141223666 1816471471871
    raw value
    foo

With this patch, you can omit those headers by setting KSTAT_FLAG_NO_HEADERS:

    $ cat /proc/spl/kstat/zfs/foo
    foo

This will be used by an upcoming ZFS patch that I'm working on.

Now that SPL is merged, I folded these changes into https://github.com/zfsonlinux/zfs/pull/7563
