I suspect there are 2 changes that would be needed. First, a shallow protocol change to 9p, where a 'bundle' tag is added, such that if an Rerror is returned for any message in the same bundle, the rest of the bundle is not executed. Second, the userspace API would need to change so that reads and writes can return without waiting for a result, this is harder, and I haven't come up with anything satisfying. ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/T769854fafd2b7d35-M08732= 5fe3d809fc254b1b283 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
