vringh_complete_multi_user(9)

📦 version 7.3.1, in nixpkgs unstable

💖 vringh_complete_multi_user — the Kernel API Manual, bestie edition 💖

Okay so picture this: we're deep in the vringh lore (that's the Kernel API Manual, iykyk) and this little icon right here is the one that tells the kernel "bestie, we are SO done with a whole bunch of descriptors at once." Not one. Many. Main character behavior fr fr. 👑

✨ NAME ✨

vringh_complete_multi_user — we've finished with many descriptors. 💅

🦋 SYNOPSIS 🦋

int vringh_complete_multi_user (struct vringh *vrh , const struct
       vring_used_elem used[] , unsigned num_used );

🌸 ARGUMENTS 🌸

  • vrh — the vring. the whole vibe. the main character of this situation 💫
  • used — the head, length pairs. literally the receipts of what got used 🧾
  • num_used — the number of used elements. how many receipts we're holding up, no cap 🔢

🎀 DESCRIPTION 🎀

So here's the tea: you should check vringh_need_notify_user after one or more calls to this function. Not before, not "eh maybe later" — after. That's the whole bit. 🫶

no cap, just remember the follow-up vringh_need_notify_user check or the vibe check fails 😭
