Given the two extra days, Linux 5.12-rc3 is larger than normal and there has been a lot of bug fixes to have landed this week anyhow. Aside from the changes stemming from the Linux 5.12-rc2 snafu, Linus Torvalds is siding with 5.12 looking like a smaller release. He noted in today's 5.12-rc3 announcement , " things look fairly normal - there's a big peak in the diffstat around the io_uring fallout from the new thread creation model, and sparc makes an unusual showing on the architecture updates side, but other than that it's all the usual things: drivers (gpu, net, usb, staging, sound... all over), architectures (x86, arm64, s390, powerpc in addition to the already-mentioned sparc), filesystems (cifs, nfs) and core kernel (networking, VM, timers, scheduler..). And the (by now) quite usual documentation and tooling updates (mainly perf tooling and selftests). "
So for now at least Linux 5.12 is looking like it will be a fairly "normal" cycle barring any major new issues from coming up in the weeks ahead. As noted in my latest report a few days ago, Linux 5.12 is looking good and stable relative to 5.11 on the many Intel and AMD systems I have been trying the post-rc2 snapshots on.
See our Linux 5.12 feature overview for the highlights of this next major kernel version that should debut as stable by the end of April.
