Yeah, 8 tags "seems" like a lot, but for a team that is working on these things, I think that is good, a bunch of people are wanting to be on the "path of blame if something went wrong" which is nice to see, they aren't just dumping the responsibility onto one person :) So I don't have any objection to this at all, and in fact, welcome it. > Our team has developed a tool that found hundreds of non-root bugs with > PoCs.

This is a good thing, thanks for doing this, it is helping both the kernel out in getting these things fixed, and these students to get them great experience in working upstream in a proper way. This is great stuff, I wish more professors and schools would do this. thanks, greg k-h
