Sigh... you really don't understand how much preliminary knowledge and prerequisites it takes to "simply" issue that command. With this answer you demonstrate exactly the mindset why so much information is behind some obscure knowledge and pointlessly so. "I know it's there means others know it's there" sigh... Not to mention that ~95% of the Earth's population doesn't speak English as the first language, how stuff is named in English is not obvious. Bad search engines, like what `man -k` has, are nearly unusable if you don't know the exact term. You'd laugh when people would recommend to you to look up words using a paper dictionary or write papers using paper encyclopedias but `man -k` is pretty much that.

To be fair, this is one of the toughest lessons for all. It makes total sense to those who know it by heart, but at the same time it makes no sense to those who honestly don't. The line between is pretty hard. Also, this is what makes me believe there is room for more discoverability-commands in Linux-land CLI. Especially for diagnostics. Since those developing it have a hard time seeing the same from a beginner point of view.

The guy is a professional dev working on Linux, are you seriously suggesting he shouldn't know what "man" does? And are you seriously suggesting that searching for "spin" is somehow arcane? https://www.google.com/search?q=linux+spin+lock+library https://www.google.com/search?q=linux+spin+lock+library pthread_spin_lock(3) is on the first page, along with a RH presentation which explains exactly why trying to roll your own userspace implementation is unlikely to be successful. The guy simply didn't do his homework, I have no idea why you are trying to defend him.
