Well, there's been some controversy about that. The problem is that it's often not clear if this is long-standing bug, or a bug which is in a particular subsystem tree --- and if so, *which* subsystem tree, etc. So it gets blasted to linux-kernel, and to get_maintainer.pl, which is often not accurate --- since the location of the crash doesn't necessarily point out where the problem originated, and hence who should look at the syzbot report. And so this has caused some.... irritation. > There is some value of testing stable trees, but any developer > will first ask for a reproducer in the latest, so usefulness of > reporting such bugs will be limited. What I suggested was to test Linus's tree, and then when a problem is found, and syzkaller has a reliable repro, to *then* try to see if it *also* shows up in the LTS kernels. - Ted
