I needed to add a custom System Request (Sys Req or SysRq) to a linux kernel some time ago. While doing so, I dug deep into how it works and I thought I’d make a quick post about it. Here is a good SuperUser answer about what a SysRq is. You may also know about SysRq via REISUB. This post has three parts: how to raise a SysRq, how SysRq works (looking into kernel code), and how to add your own SysRq.

    Let’s talk about how I don’t like Linus tech tips again. I know your can’t wrap your mind around me having my own opinion and posting one sentence about it

    THIS IS MUCH BETTER

      Yeah you’re really showing them how you have the moral high ground by following them to other posts and harassing them there… ???

        Who said I wanted moral high ground anymore? 🤔

          You’re behaving like an unhinged stalker, though.

          We all get it, you have an axe to grind with jet, but like maybe keep it to private messages then? What’s the point with following them around and spewing this stuff on completely unrelated communities?

            He gave me a long bit of the opposite of what I asked for. I owe him the same attention.

          You were talking about them not being able to comprehend the fact that you have your own opinion, so that was my guess.
