From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Title make little sense to me.
A lot of the security fixes since spectre have focused on exploiting speculative execution (a key CPU performance feature) to cross security boundaries. Defeating speculative execution when switching from user to kernel space (for example) adds a lot of overhead.
The new kernel add controls so that machines that don't need to worry about these exploits to disable the performance killing fixes.
I get the concept. Title is written so badly that's really unreadable make no sense and confuses even people who know a bit on the subject.
The word "land" should be relaces, because it stck with controls and lose its meaning. Also, repeating control again adds to the mess.
Agreed. The headline is terrible. Headline Case Doesn't Help Either.
