This is a simple hoist, right? Sorry, I will restore the casts to how it was earlier. I don't remember the exact reason for changing them. I thought I had seen some compilation issues. But after restoring them, I see that the code compiles fine. -- chandan

Maximum values associated with extent counters i.e. Maximum extent length, Maximum data extents and Maximum xattr extents are dictated by the on-disk format. Hence move these definitions over to xfs_format.h.
