Last week, Linus Torvalds He launched a sixth RC of the kernel version that you are currently developing with the good news of having corrected a regression in its performance. At that time we thought that everything was on the right track, but a few hours ago launched Linux 5.9-rc7 and he has encountered problems again that he must solve. Being in what is usually the last preliminary version, everything seems to indicate that there will be a delay.
Actually, it is not that you have encountered any serious problems; The thing is, the solutions to all known issues came a bit late, so if the Linux dad isn't feeling extra optimistic and something tells him that everything is bug-free, will release an eighth Release Candidate next Sunday, which would not change anything for Ubuntu users as we will explain later.
Linux 5.9 is coming October 11
So we finally have all the problems I know of solved - the solution for the VM problem that I mentioned in the rc6 announcement is here, as is the solution for the slab corruption problem that was discussed separately, along with another bug silly page lock -Fix overlay. But even though I know of the remaining activation issues now, the fixes came quite late. So unless I'm feeling incredibly optimistic and / or a burning bush tells me everything is bug-free, my plan now is that I'll do another rc next Sunday instead of the final 5.9 version. And by the way, no more burned bushes. We are somewhat sensitive to those on the west coast at the moment.
As we had mentioned, Ubuntu users will not notice anything, because the current Focal Fossa is using Linux 5.4 and Groovy Gorilla, scheduled for October 22, it will stay on Linux 5.8. We can install the 5.9 series manually, of course, but that is another matter. In any case, the important thing is that everything works as well as possible, and that is what Torvalds plans.
