In collection_list_range, use an empty vector to pass into
collection_list_partial. collection_list_partial stops
listing when the output vector exceeds the specified max.
If this happens before we hit the end of the range,
collection_list_range will spin forever.

At (1): Potentially overflowing expression "layout->fl_stripe_count.operator unsigned int() * layout->fl_object_size.operator unsigned int()" with type "unsigned int" (32 bits, unsigned) is evaluated using 32-bit arithmetic before being used in a context which expects an expression of type "uint64_t" (64 bits, unsigned). To avoid overflow, cast either operand to "uint64_t" before performing the multiplication.
