Strange : at fuse_statvfs+117 I have an strlcpy(), not strlen().

The source of the strlcpy() is the file system type, which, as far
as I understand, is provided by /usr/lib/fs/ntfs-3g/fstyp, the
copy length is the constant 16, no strlen() used.

On my computer I get :
[root at openindiana amd64]# /usr/lib/fs/ntfs-3g/fstyp /dev/dsk/c5t2d0p1
ntfs-3g
