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.

Maple Tree also recently caused intermittent failures in some of my CPU-intensive tasks, in such an obscure way that I only found out by dumb luck that it was a kernel bug. I expect it will be great eventually, but it's feeling pretty rough at the moment. I'm thinking this code should have had more testing and maturing before going mainline.
Damn. If the Maple Tree code is bugging out under CPU-intensive tasks, that would explain a lot about how my system's been behaving since I moved to 6.1. Thanks for the heads-up, and I guess I should compile another new kernel.
Rcu is mostly broken, it's been a nightmare for a decade, building on top of that seems suicidal.
I know rcu failures are just symptoms of other issues, but building on top of it doesn't help matters.
