    Description

      As discussed in review board: https://reviews.apache.org/r/70465 . Apache9 has an comment:

      I think with the new reference counted framework, we do not need to treat rpc reference specially? Just release the bucket from oldest to newest, until we can find enough free space? We could know if the space has been freed from the return value of release ? Can be a follow on issue, maybe.

      Now, we'll choose those non-RPC refered block to mark as evicted, maybe can simplify the logic here , just as Apache9 said.
