relocate_inodes(), relocate_inode(), especially the $MFT part. There is a
strict order in what and when is relocated. At some point ntfs_volume is
mostly used only for reading and a new NTFS gets written.
Anything must be modified before it gets relocated, never afterwards.
Your change broke this very serious rule.
