You don't have to review their code, but discouraging the > posting seems wrong. I have a long history of Intel using me for their basic "find the obvious bugs" review process for new driver subsystems and core changes. When I see new major patches show up from an Intel developer without _any_ other review from anyone else, directed at me, I get suspicious it is happening again. If you note, Intel is the _only_ company I say this to their developers because of this problem combined with the fact that they have a whole load of developers that they should be running things by first. And yes, to answer Dan's point, we do want to do review in public. But this is v6 of a core patchset and there has been NO review from anyone else at Intel on this. So if that review was going to happen, one would have thought it would have by now, instead of relying on me to do it. And yes, I am grumpy, but I am grumpy because of the history here. I am not trying to discourage anything, only to take ADVANTAGE of resources that almost no other company provides. Hope this helps explain my statement here. thanks, greg k-h _______________________________________________ Linux-nvdimm mailing list Linux-nvdimm@lists.01.org https://lists.01.org/mailman/listinfo/linux-nvdimm
