The number for raid1/10 doesn't need to be the same. But if we don't move the number to a generic header, the third patch will become a little more complicated. I eventually ignored this issue. If we really need different number for raid1/10, lets do it at that time. I think your suggestion that moving the number to raid1-10.h makes sense, and add a comment declaring the number isn't required to be the same for raid1/10. Thanks, Shaohua
