    /**
     * block_index = offset_in_virtual_disk / block_size actual_data_offset = blocks_map[block_index]*block_size+metadata_size+offset_in_block
     * The blocks_map will take up blocks_in_image_max * sizeof(uint32_t) bytes; since the blocks_map is read and written in a single operation, its size needs to be limited to INT_MAX; furthermore, when opening an image, the blocks_map size is rounded up to be aligned on BDRV_SECTOR_SIZE. Therefore this should satisfy the following: blocks_in_image_max * sizeof(uint32_t) + BDRV_SECTOR_SIZE == INT_MAX + 1 (INT_MAX + 1 is the first value not representable as an int) This guarantees that any value below or equal to the constant will, when multiplied by sizeof(uint32_t) and rounded up to a BDRV_SECTOR_SIZE boundary, still be below or equal to INT_MAX.
