💅 ionic_queue_length(9)

okay bestie so this is a page from the Kernel API Manual and it's about literally one tiny little function that tells you how long a queue is. that's it. that's the whole vibe. but she's iconic so let's get into it 🎀

✨ NAME ✨

ionic_queue_length — get the current length of the queue 🦋

like. the length. of the queue. right now. present tense. no cap.

🌸 SYNOPSIS 🌸

u16 ionic_queue_length (struct ionic_queue *q );

she returns a u16 and she takes exactly one pointer. minimalist queen 👑

🎀 ARGUMENTS 🎀

  • q — the queue structure 💖 this is the queue we're measuring, the main character of the whole operation

💜 DESCRIPTION 💜

so like. this gives you the length of the queue. but heads up — it is only valid for to-device queues. periodt. if you're out here calling this on some other kind of queue you are not in her target audience and she is not responsible for what happens 🙈

⭐ RETURN ⭐

the length. that's the answer. she tells you the length. slay 💅

🌈 SEE ALSO 🌈

the whole friend group, honestly. the kernel file ./drivers/infiniband/hw/ionic/ionic_queue.h defines struct ionic_queue(9), and then there's the rest of the squad:

ngl bestie, if you're reading this page you should probably also read ionic_queue_empty(9) and ionic_queue_full(9) because the three of them together are giving "is my queue okay?" energy check 💀

and that's the whole page!! like genuinely, she's short and she knows exactly what she is 🧚

anyway, this masterpiece lives over at ./drivers/infiniband/hw/ionic and it's dated October 2026 — so screenshot it, cite it, frame it, whatever. mwah 💖✨🍓
