Bug#865462: extlinux: fails to boot from Btrfs filesystem

Hi Marek & Peter,

thanks a lot for not only reporting this issue but also finding and
testing the fix.  I can also reproduce the problem and confirm that the
mentioned commit fixes the issue.

I am in the process of adopting syslinux as part of the debian-cd
team.  A fixed version will probably be uploaded to unstable soon.  I
will also try to get this included in the next point release (9.3),
but we're obviously careful about changes to bootloader code so I can't
promise anything.

Regards
Lukas
