Desktop-deprived Linus Torvalds releases first release candidate of ‘not huge’ kernel 5.17

(2022/01/24)


The first release candidate for version 5.17 of the Linux kernel has rolled off the production line – despite fears that working from a laptop might complicate matters.

Emperor Penguin Linus Torvalds is currently on the road and, when [1]announcing the release of Linux 5.16 predicted that the version 5.17 release merge window would be “somewhat painful” due to his travels, and use of a laptop – something Torvalds said “I generally try to avoid.”

Torvalds’ laptop aversion comes from the fact that he likes to do lots of local testing on his [2]beastly workstation powered by a 32-core AMD Ryzen Threadripper. Linus’ lappie appears not to match his desktop, so he ends up using more automated build testing in the cloud.

“And so [i] really hope that everything has been properly cooking in linux-next so that there are no unnecessary issues that pop up when things hit my tree,” he wrote.

Torvalds’ fears appear not to have materialised, as his [6]announcement of version 5.17 rc1’s debut states “Everything seems to have gone fairly smoothly.”

The maintainer in chief opines that version 5.17 “doesn't seem to be slated to be a huge release, and everything looks fairly normal.” Torvalds noted “a bit more activity than usual in a couple of corners of the kernel (random number generator and the fscache rewrite stand out)”, but there’s nothing else he flagged as significant.

Others may beg to differ: The Register reckons changes that let RISC-V silicon address 64TB of physical memory sets the stage for interesting future server developments. Additional support for Intel’s Alder Lake CPUs, which mix-and-match performance and more modest cores, is also important.

The addition of the Real-Time Linux Analysis (RTLA), code [11]billed making life easier for users and developers “to collect performance and trace data, helping fine-tune their systems/algorithms” will also be handy.

Torvalds’ post apologised to anyone who missed the closure of the merge window for this release, because his travels meant he created the release candidate a few hours ahead of his usual timing. While lightly scalding those who left it so late in the two-week window to submit their code, he added: “there's always 5.18. Never fear - we'll not run out of numbers.”

Might that be a reference to his past musings on the significance, or lack thereof, for version numbers? When Linux 3.19 emerged, Torvalds [13]capped version numbers at x.20 in reaction to version 2.x’s culmination at version 2.6.39. As the 4.x series reached its teens, Torvalds again [14]mused that version names are meaningless and said he doesn’t like to be predictable when it comes to naming. We should know what monikers he has in mind around mid-year if kernel development proceeds at its usual pace. ®
