That is just the HEAD commit on linux-next that day. If you fetched linux-next after I released next-20180814 yesterday, then it would have a different HEAD commit. If you check out the tag next-20180813, you will get the above HEAD commit. > On the dashboard link you can see that it also happened on a more > recent commit 4e8b38549b50459a22573d756dd1f4e1963c2a8d that I do see > now in linux-next. Which is just the HEAD commit of next-20180814. Linux-next is rebuilt every day based on Linus' tree of the day, followed by merging all the other branches, so its HEAD is different every day. --=20 Cheers, Stephen Rothwell --Sig_/I8o_MI0gUdV6LA/b8SpCkwp Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- iQEzBAEBCAAdFiEENIC96giZ81tWdLgKAVBC80lX0GwFAltzb6gACgkQAVBC80lX 0GwWkQgAkQotgz77Nk2wu/Zy8M2g8vT+tez8J0FYXe5IhrCyNKujLIpavlSb+HS5 gVzyxnswvPs89Bl95q7VhYGnTnu/+A4wWFV56QRlKgqSZRtClBkMX84UB92KQpaF e5SPnf59xZzz3auIzgz5YAnq8jQ3xLSkCNH/8fUH1cnqPmp3nW0iQFNQvX7zgIP1 It5m4QJhm6b0BNM0WJ1ePPU0Kg2oBYRjYnH4JQBaVVi5RIHYJJEwgNEeIkH/NePB NgoWiKEqo7Fw4LkxDeCpDR21/B12ZEbigLx1DnyZOTa3vTMnceoJ8DQbUEcOUjLh r6/kTOgBaN71fXOfh+Aso/UbYUt8QA== =iwCW -----END PGP SIGNATURE----- --Sig_/I8o_MI0gUdV6LA/b8SpCkwp--
