Sorry for the delay. Did you saw any performance problem?
I know it would be better than old but your assumption depends on the
implmentation of zs_create_pool so if we changes(for example,
revert 9eec4cd if compaction works well), your patch would be void.
If it's not a critical, I'd like to remain it as generic and doesn't
contaminate git-blame.

Thanks.
