On mutexes, semaphores and queues

Please excuse if this is inappropriate for the kernel category, but relates to many questions posted in this forum.

I wrote a blog post a few years ago on the difference between semaphores, mutexes and queues, and their motivations. It has become the most read article on the Percepio website. Since there seems to be a lot of interest for this topic, I’m sharing it here too.

Do you have other perspectives on this topic, that perhaps was overlooked in the original post?

Thanks for the link - no doubt we will use it in the future in answer to relevant questions on this forum so users can get the information they need.
