First in increases the file size with a truncate by 2 * l2Capacity. It then checks that all the bits in the new allocated space are set to 0. Then it writes data to it to verify writes are possible. After that it truncates it back to the original size. Then it truncates it back to the original size + 2 * l2Capacity and verifies that the again all bits in the new allocated space are 0 (so that the before written data is set to 0 again). |
