The original code works fine but the issue is that static checkers complain about this: ~(u16)(OFFSET_UNITS - 1) In that expression the cast to u16 is a no-op because we cast the value 15 to a u16 but then type promotion rules automatically cast it back to an int and then we do the bitwise negate. It's cleaner to use the kernel's ALIGN() macro instead.
