I still have a big outstanding question: Does the failed notify API make sense? I'm leaning no, but want another opinion before I go rip it back out. To summarize: it notifies a watcher if it was slow to respond to an earlier notify and caused the notifier to time out. Counterargument: if the notifier wants to tell everyone they saw a timeout, they could send another notify; at least then they would know if the second piece of information was delivered (quickly). I don't think that librbd or rgw will make use of it. The last bit of work remaining is to migrate RGW over to the new API and make it use watch_check(). Will work with Yehuda on that, but in the meantime, this is ready for review! 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
