https://github.com/ceph/ceph/pull/5534 does two things: (1) combine the buffer::raw reference count and buffer into a single allocation (ala make_shared), and (2) convert buffer::list into an intrusive_list, while embedding N (=3) buffer::ptr's in the buffer::raw so that most buffers require only 1 allocation (provided they aren't on more than N lists). This needs a rebase, and some benchmarking. But before I pull it up, is this the right direction? I saw little benefit from (2) after doing (1), but I was doing a really simple microbenchmark. Do we want both, or just 1, or is there an alternative we should consider? sage -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
