Fedora regularly rebases to the latest stable kernel, usually by .2 or .3 release; but 4.18 has had quite a busy series of rapid fire updates, so it's already at 4.18.5. I expect to see that in Fedora 27 and 28 updates-testing this week. Usually it's possible to get a build of current stable or mainline kernel in a day or two on Fedora, through koji. And through updates-testing repo (opt in) a few days later. And through updates (enabled by default) anywhere from 1-5 days later. The system depends on testers using updates-testing repo to give +/- points to each tested package, and the kernel comes with a higher than usual minimum number of points and time delay to avoid regressions. You can (manually) install kernels in Koji which don't always show up right away in the updates-testing repo. So you'll see 4.18.5 there for fc29 which can be installed on Fedora 28 (I've been doing this for weeks). And you can also manually install 4.17.19 which is already built there, just not yet in updates-testing. https://koji.fedoraproject.org/koji/packageinfo?packageID=8 https://koji.fedoraproject.org/koji/packageinfo?packageID=8 4.17.18 has already gone stable in the updates repo, so anyone doing a 'dnf update' now will get it. https://bodhi.fedoraproject.org/updates/?packages=kernel https://bodhi.fedoraproject.org/updates/?packages=kernel
