Parameter size of function get_cluster() is of type unsigned long. It makes
no sense to convert actsize to int before passing it to get_cluster as
size.

If the type is unsigned long, the explicit cast here seems redundant.
actsize is of type l_off_t. As long as loff_t does not have more bits
than unsigned long you are right. But the C language does not require
this to hold true.
But why shouldn't we use the same type loff_t in the interface of
get_cluster. I will update the patch.
Best regards
Heinrich
