📦 version 7.3.1, in nixpkgs unstable

hii bestie 💖 welcome to the ring_buffer_..._overrun_cpu(9) page from the Kernel API Manual. It’s giving deep kernel ring-buffer lore, but make it cute. No cap, every detail is staying right here. 🫶

       *buffer , int cpu );

🎀 ARGUMENTS 🎀

  • buffer — the ring buffer. That’s the whole assignment, icon.
  • cpu — the per CPU buffer to get the number of overruns from. Per-CPU specificity is the main character here.
