The original code put five u32 before a u64 expansion[10] array. Five is odd, this will cause trouble in the extension of the structure by adding new features. This patch moves to use u8 for reserved field to avoid future alignment risk. Meanwhile, it also clears the memory of struct map_benchmark in tools, otherwise, if users use old version to run on newer kernel, the random expansion value will cause side effect on newer kernel.
