Aaron Gao 10d7546961 set readahead buffer size from roundup(user_size) + 4k to roundup(use…
Summary:
Users usually set readahead buffer to a multiple of 4k, more than that, usually a multiple of blocks.
So previously we set real buffer size 512 * n + 4k, which may introduce an additional block reading.
Closes https://github.com/facebook/rocksdb/pull/2138
