           fact that the vfs and ntfs inodes are one struct in memory to find
           the ntfs inode in memory if present.  Also, the ntfs inode has its
           own locking so it does not matter if the vfs inode is locked.
+        - Fix bug in mft record writing where we forgot to set the device in
