Description ncopa 2016-06-30 10:55:41 UTC 
On Alpine Linux (with musl libc) the used size of ntfs partition is calculated wrong due to sscanf is using %Ld as modifier. POSIX says that %lld should be used for long long.

Hi Natanael,

Thank you for the patch.  I have also added changing the use of scanf
directive "%Lx" to "%llx" in jfs.cc too.

Successfully tested on CentOS 5 and Ubuntu 16.04 LTS.  Read a range of
file system usages: ext*, fat*, jfs, linux_swap, ntfs, xfs; read ntfs
>= 5 GIB in size; progress of ext* create and copy using e2image.

The following commit has been committed to upstream GIT and will be
included in the next release of GParted.

Fix sscanf modifier for long long (#768239)

Thanks,
Mike
