finish_notification(9)

💅 finish_notification(9) 💅

okay so bestie, welcome to the Kernel API Manual — yes that's the whole manual name, and yes this little function lives rent-free in it. buckle up, it's a short one but it's iconic 🎀

---

✨ NAME ✨

finish_notification — literally just wraps up the notification process. that's it. that's the vibe. periodt 💅

---

🌸 SYNOPSIS 🌸

void finish_notification (struct vdo_completion *completion );

no return value, no drama, just vibes and a single pointer 🦋

---

💖 ARGUMENTS 💖

• completion — the flusher completion. that's the one. your main character struct of this whole function 🫶

---

🧚 DESCRIPTION 🧚

so here's the tea ☕ — finish_notification finishes the notification process. how, you ask? it does two (2) things, and honestly? slay:

1. it checks if any flushes have completed ✅
2. then it starts the notification of the next flush request — but only if one came in while the current notification was already in progress 🔥

like, it's giving "clean up, then see if anyone's waiting in the group chat" energy, yk? very considerate, very polite, no cap 💜

also important, don't skip this part: this callback is registered in flush_packer_callback. that's the plug. that's where it gets hooked up. iykyk ✨

ngl, this is a callback — so you're not out here calling it yourself in your main character arc. it gets invoked through the registration, bestie. respect the flow 🙈
