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.

It's frustrating that there isn't much of an effort to turn Linux into more of a microkernel. Instead the kernel just keeps getting bigger with even more subsystems and modules that can be exploited.
Systems built on microkernels exist, you know. See Redox.

A microkernel wouldn't be that useful without a stable module interface, which won't be coming anytime soon.
There is at least already a userspace PCIe API. And USB and so on.
