I'm not talking about stuff like intending or naming schemes, I'm talking about real bugs like missing error codes or NULL dereferences. People do count tags so we might as well add them for worthwhile behavior. > > So I don't think "Fixes-from" (whatever that means) or > "Reported-by" make sense for this type of update. > Earlier today I forwarded a kbuild Smatch warning where someone had used "sizeof(0)" instead of "0" but because the patch was already applied, that means I got Reported-by credit. If the kbuild-bot could have reported the bug before the networking people applied it that's more valuable but I get less credit. It's a perverse incentive. Also I sort of don't like the Reviewed-by tag. I see a lot of people adding Reviewed-by but I've never seen them point out a bug during the review process so that seems pretty worthless. But Fixes-from means that person knows what they're talking about. regards, dan carpenter
