I'm starting on adding systemtap trace points to the osd. https://github.com/athanatos/ceph/tree/wip-osd-stap has some initial build changes and a single tracepoint in OSD::handle_op. I'll ping the list when I've got more. -Sam -- 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
