- * WARNING: This program might not work on architectures which do not allow
- * unaligned access. For those, the program would need to start using
- * get/put_unaligned macros (#include <asm/unaligned.h>), but not doing it yet,
- * since NTFS really mostly applies to ia32 only, which does allow unaligned
- * accesses. We might not actually have a problem though, since the structs are
- * defined as being packed so that might be enough for gcc to insert the
- * correct code.
- *
- * If anyone using a non-little endian and/or an aligned access only CPU tries
- * this program please let me know whether it works or not!
