"Ring the bells, sound the trumpet, the Linux 6.19 kernel has arrived. Linus Torvalds announced that "6.19 is out as expected -- just as the US prepares to come to a complete standstill later today, watching the latest batch of televised commercials." Because while the big news in Linux circles might be a new Linux release, Torvalds recognizes that for many people, the "big news [was] some random sporting event." American football, what can you do?"
"With 6.19, the 6.x line ends on .19, mirroring the 3.x and 5.x series before the project increments to 4.0, 6.0, and now 7.0. Mind you, Torvalds confirmed that the next kernel after 6.19 will be branded Linux 7.0, not because of any major upgrades, but because "I'm getting to the point where I'm being confused by large numbers (almost running out of fingers and toes again), so the next kernel is going to be called 7.0.""
Linux 6.19 has been released and opens the merge window for the next kernel. The 6.x line concludes at .19 and the following kernel will be branded Linux 7.0 despite no major internal changes. The release adds initial support for Intel's linear address-space separation (LASS) to mitigate speculative execution and side-channel attacks like Meltdown and Spectre. LASS more strictly isolates kernel and user memory to reduce privilege-escalation risks. The release also adds support for Arm's Memory System Resource Partitioning. Several performance boosts are included, with the single biggest improvement targeted at cloud deployments.
