Hello, It's been more than half a year since the initial posting of the patchset and we are now at the fourth iteration. There have been some reviews around specifics (should be all addressed now except for the ones Andrea raised on this iteration) but none at high level. There also were some in-person and off-list discussions. Some, I believe, are addressed by the cover letter but it'd be nonetheless useful to delve into them on-list. On our side, we've been diligently experimenting. A lot of our earlier experiments were focused on improving work conservation which led to the CFS shared runqueue patchset that David Vernet is currently working on. The workqueue experiments which led to PeterZ's SIS_NODE patch was also informed by the same work conservation experiments. We also played with soft affinity which is inspired by Julia's nest scheduler. Another thing we recently learned was that at least for our web workload, L1/2 locality doesn't matter much. This is an area of on-going experiments. We are comfortable with the current API. Everything we tried fit pretty well. It will continue to evolve but sched_ext now seems mature enough for initial inclusion. I suppose lack of response doesn't indicate tacit agreement from everyone, so what are you guys all thinking? Thanks. -- tejun
