Hi Namjae,

  Thank you for your kind words and for suggesting this work.

  Yes, I would be happy to work on 64-bit cluster support for NTFS. I 
will first investigate how to implement it, and then develop and test 
the changes based on the latest ntfs-next branch.

  I will keep you updated on my progress.

Best regards,
Baolin.
