i40e_irq_affinity_release(9)

📦 version 7.3.1, in nixpkgs unstable

💅 i40e_irq_affinity_release(9) — Kernel API Manual, section 9 ✨

okay so bestie, this is a tiny little callback in the i40e driver family — like, the smallest little function but it's got a job, and the job is "hey girl, you're unsubscribed 💌". It lives in the Kernel API Manual (section 9), so it's ✨kernel-internal✨ and not something you'd ever type into a shell. iykyk.

🌸 NAME 🌸

i40e_irq_affinity_release — Callback for affinity notifier release. that's it, that's the whole vibe 🎀

✨ SYNOPSIS ✨

void i40e_irq_affinity_release (struct kref *ref );

no return value, it's giving "void and unbothered" 💅

🫶 ARGUMENTS 🫶

  • ref — internal core kernel usage. like, genuinely internal — the kernel core is the one handing this over, so don't overthink it, it's not your problem, it's the core's problem 🫶

🦋 DESCRIPTION 🦋

So here's the tea: this is a callback function that the irq_set_affinity_notifier function uses. Its whole entire purpose is to slide into the current notification subscriber's DMs and be like "bestie… you will no longer receive notifications 😭". That's it. That's the function. It's the polite little goodbye text of the IRQ affinity notifier world 💌

No cap, it's short, but it's iconic — someone has to break the news, and apparently that someone is i40e_irq_affinity_release. main character energy fr fr 👑

🔥 SEE ALSO 🔥

Okay so this is the part where the manpage just. keeps. going. The kernel file itself lives here — go read it, it's a whole journey:

  • ./drivers/net/ethernet/intel/i40e/i40e_main.c

and then, strap in, because the cross-reference list is long long. Not me listing every single one though — every single one, exactly as written, no skips, no cap 💀

like… that's the whole extended i40e friend group 😭 every last one of them, accounted for, no one left on read 🫶

and that's the page, bestie!! 🎀 run out of a source dir of ./drivers/net/ethernet/intel/i40e, dated October 2026 — stay hydrated, go read i40e_irq_affinity_notify(9) next, and ily for reading a kernel manpage for fun ✨💖🦋
