Duplicate of 10-years-old outstanding patch at [1].

I'm not speaking of the patch itself but rather on unfortunate state
of ntfs subsystem. It seems like the maintainer is MIA (has not
responding to patch submissions for a long time). Some trivial
patches, however, are merged through mm tree.

Konstantin (from newer ntfs3 subsystem), Andrew, would you like to take a
look on this orphaned subsystem (and help reviewing)? I'd like to send
MAINTAINERS update if it turns out to be the case.

Thanks.
