In 2017, Linux rules computing

 The Linux Foundation reports that Linux runs 90 percent of the public cloud workload, 82 percent of the world's smartphones, 62 percent of the embedded market, oh and a mere 99 percent of the supercomputer market. All that rests on the Linux kernel.

"The Linux kernel is one of the largest and most successful open-source projects that has ever come about. The huge rate of change and number of individual contributors show that it has a vibrant and active community, constantly causing the evolution of the kernel in response to number of different environments it is used in. This rate of change continues to increase, as does the number of developers and companies involved in the process; thus far, the development process has proved that it is able to scale up to higher speeds without trouble."

 Good news :)

Over the past year, the kernel has been updated through merged changesets, new drivers, hardening and testing.
