If you're the code for initialising the DRAM controller then sure, that's pretty intimidating. But this is all happening much later, we're part of an operating system, we were already loaded from disk. I don't know what you're trying to say. The code which is written here that we are discussing is in a constrained environment where the regular kernel runtime facilities are not all available. This was cited as one of the reasons cited for open coding a very simple algorithm. > > And evidently they do need a stable sort. > How so? From reading comments from patch author here.
