The correct version is b*, it's indeed back, but in a completely reworked way, as I wrote to Lorenzo yesterday. Pre-existing reports are now limited to the first non-rfc version of the patchset, they are limited in numbers per patch (1-2), they are _deduplicated and posted strictly once per issue_. Re consulting the problem is that there are several hundreds maintainers with drastically different views. If we'll wait for everybody's agreement each time, nothing will ever move. So I have to make some decisions like this on my own. And, yes, some of them will be wrong or not perfect. I do fix/adjust things constantly. But some patience would be nice. Btw now you can delegate access to bugs to people outside of MAINTAINERS. > I'm sorry if I made you angry, but I hope you can see how I suspect (b) and why > it would make me angry. No problems. I understand the problem with the maintainers load right now. Thanks
