     ("dm raid: round region_size to power of two")
    intended to make sure that the default region size is a power of two.
    However, the logic in that commit is incorrect and sets the variable
    region_size to 0 or 1, depending on whether min_region_size is a power
    of two.
    
    Fix this logic, using roundup_pow_of_two(), so that region_size is
    properly rounded up to the next power of two.
