The Linux kernel is an open source monolithic Unix-like computer operating system kernel. The Linux family of operating systems is based on this kernel and deployed on both traditional computer systems such as personal computers and servers, usually in the form of Linux distributions, and on various embedded devices such as routers, wireless access points, PBXes, set-top boxes, FTA receivers, smart TVs, PVRs, and NAS appliances. The Android operating system for tablet computers, smartphones, and smartwatches uses services provided by the Linux kernel to implement its functionality. While the adoption on desktop computers is low, Linux-based operating systems dominate nearly every other segment of computing, from mobile devices to mainframes. As of November 2017, all of the world’s 500 most powerful supercomputers run Linux.
The Linux kernel was conceived and created in 1991 by Linus Torvalds for his personal computer and with no cross-platform intentions, but has since expanded to support a huge array of computer architectures, many more than other operating systems or kernels. Linux rapidly attracted developers and users who adopted it as the kernel for other free software projects, notably the GNU Operating System. The Linux kernel has received contributions from nearly 12,000 programmers from more than 1,200 companies, including some of the largest software and hardware vendors.

Linux Kernel 5.19 RC3 released.
It's Sunday afternoon, which means it's time for another rc release. 5.19-rc3 is fairly small, and just looking at the diffstat, a lot of it ends up being in the documentation subdirectory. With another chunk in selftests. But we do have real code changes too, fairly evenly split between drivers, architecture fixes, and "other code". That other code is mostly filesystem fixes, but also some core kernel and networking. Full shortlog appended for your enjoyment, but so far everything looks fine. Knock wood, Linus
