Core system code doesn't move at quite the same pace as the latest vibe coders, and thankfully so, as it needs to be stable, efficient, and battle-tested. However, sometimes delays can get a little ridiculous, as was the case with the documentation for Linux's contemporary filesystem API. As noted by Phoronix, it was over a six-year wait for the info to appear in the standard man-page (manual page) documentation.
The tale goes like this: in 2019, Linux got the minty-fresh new filesystem mounting API, with the main "fsconfig," "fsmount," and "fsopen" calls replacing the old, monolithic "mount." This made it a lot easier for developers to use the new functionality, enjoying cleaner code, better error handling, and the ability to output proper error messages, rather than the cryptic "mount failed."
