Does syzbot only build/test a single kernel arch/config? > Stephen, Dmitry - is there some way linux-next could possibly kick out > trees more aggressively if syzbot can't even boot? Of course that could be done if I knew that there were problems. From memory and my mail archives, I was only cc'd on 3 problems by sysbot since last November and they were all responded to by the appropriate maintainers/developers. Currently, when I am cc'd on reports, if they are also sent to who seem like the appropriate people, I just file the report assuming it will be dealt with. > Kicking trees out of linux-next and making noise if they cause syzbot > failures might also make some maintainers react more.. That may be true, but in some cases I have carried fixups/reverts/older versions of trees for quite some time before things get fixed. But at least if that happens, I do tend to remind people. --=20 Cheers, Stephen Rothwell --Sig_/n_a=u.Ml/2pJE9BUl5munRl Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEENIC96giZ81tWdLgKAVBC80lX0GwFAl6Pr+8ACgkQAVBC80lX 0GwCHgf/ZRqpSjhVVe+fYBrYmpnwfFnrL/Oh72lh7tck0j1YEjzwMCFBfN5pijAv WMI80UlZlDlj3L6ErGNnlkkHuQr+qDmXXPfPFGHXkVYKxf7Wm4653D+xjz5ON1qH ynkN7384PaKE/o23MokpEvxP8/l7pPMhT0nQeJtY76c/tPDaBVg5vN9cOH+4poZm KvExSzx242t12kd0m0tqCQSnnNVJKdOdZ5XJ/oCc8oaq8n8t095FfXM+TNffwHkg N+U17MlvBmmsOetOZ+MhV8BzKyixzKyYgDiNnn8FBgyhCcEae1LEeUaW0qM/um4V nPrJdvinKjPgPth7YtGGTcHG2iBMsw== =2xaa -----END PGP SIGNATURE----- --Sig_/n_a=u.Ml/2pJE9BUl5munRl--
