ib_device_put(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ib_device_put — the release the reference girlies

okay so this is a page from the Kernel API Manual, bestie — manual section 9, kernel developer land 🧚✨. And honestly? The name says it all: ib_device_put is literally Release IB device reference. Short function. Big consequences. Let's get into it 🫶

✨ NAME ✨

ib_device_put — release an IB device reference 💖

🦋 SYNOPSIS 🦋

void ib_device_put (struct ib_device *device );

that's it. that's the whole vibe. void return, so like… she doesn't report back. she just does 💅

🎀 ARGUMENTS 🎀

  • device — the device whose reference you're releasing, bestie. drop that ref like it's hot 🔥

🌸 DESCRIPTION 🌸

So here's the tea ☕: ib_device_put releases a reference to the IB device. Why do we care? Because while refs are held, that device can't be unregistered, and it definitely can't be freed 😭. Every ref you're holding is a little "not yet, she's still busy" sticky note.

Release it with ib_device_put and you're basically saying "okay, I'm done, she's free to go" — which lets the device be unregistered and eventually freed ✨.

no cap, this is the cleanup step. hold a ref, do your thing, put the ref back. periodt 👑

💜 SEE ALSO 💜

Think of this as the group chat the function is in — the whole ./drivers/infiniband/core/device.c crew, plus the friends in section 9 🦋:

like, the whole roster 😭 she knows everybody.

and that's the page, bestie! 🎀 this lil icon lives in ./drivers/infiniband/core and the stamp on her birth certificate says October 2026 — so go forth, put that device ref back, and let her be free 🌈💖 mwah, bye 🫶✨
