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.

I remember there were talks about merging the patches and making it an option when building. I don't know the current status of that.

On real time operating systems, like freertos, not only the kernel is real time but everything else is too. Like: you can guarantee your call on the I2C and SPI won't take more than 5ms, for example, even with hardware issues. The whole environment is built around the hardware realtime concept.
