But I really appreciate the time spent on the additional conversions. One question I have is whether we shouldn't just be honest and add support for linkat, symlinkat, and mknodat in one go instead of being shy about it. uring does already have mkdirat, renamat2(), and we already have open(). It seems kinda silly to delay the others... Unless there's genuinely no interest or need of course. Christian
