From: "Xiong, James" <james.xiong@xxxxxxxxx> This series 1) align the reuse buffer size to page size instead. The goal is to reduce memory penalty (up to 25% when reuse is enabled ) while maintain similar performance. A potential overhead is: since a bucket now contains cached buffers with difference sizes, we need go through the list to search for a suitable buffer for reuse. However since the buckets get cleaned up regularly and the older cached buffer are removed, the list should not be long and the performance impact should be minor. 2) fix a bug that a bucket size instead of the requested size was ALWAYS used for buffer allocation even when bo_reused is disabled.
