__fw_devlink...ng_consumers(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, you clicked into a kernel API page, and yes the manual name is literally Kernel API Manual — we're in the big leagues now. this one is a function in ./drivers/base/core.c and it's lowkey about rescuing "dangling consumers" from being orphaned, which honestly? main character energy. let's get into it 🫶

🌸 NAME 🌸

__fw_devlink_pickup_dangling_consumers — Pick up dangling consumers, fr fr. that's the whole vibe check of this function 💖

✨ SYNOPSIS ✨

void __fw_devlink_pickup_dangling_consumers (struct fwnode_handle
*fwnode , struct fwnode_handle *new_sup );

she takes two struct fwnode_handle * args and returns void, so like… no return value, no notes, she just does the thing and dips 💅

🎀 ARGUMENTS 🎀

  • fwnode — the fwnode you're picking dangling consumers up from. like, this is the one being examined, bestie 🦋
  • new_sup — the fwnode of the new supplier. the glow-up destination, iykyk 👑

🦋 DESCRIPTION 🦋

so here's the tea ☕ and the logic is genuinely iconic:

if the fwnode has a corresponding struct device and that device supports probing — and yes, that means it's been added to a bus — then we want to let fw_devlink create MANAGED device links to this device. so in that case? leave fwnode and its descendant's fwnode links alone. hands off. she's fine. don't touch 💀

otherwise, you move its consumers over to the new supplier, new_sup. no cap, that's the whole move — dangling consumers get picked up and re-homed 🌈

ngl this is exactly the kind of "if you're properly attached to a bus, you're self-sufficient; otherwise come here little orphan" energy we love to see 🥺

and the source file for all of this drama is the Kernel file ./drivers/base/core.c 🧚

⭐ sign-off ⭐

that's the page, bestie — sourced from ./drivers/base, dated October 2026, and the header/footer both spell the name as __fw_devlink...ng_consumers(9) because the man page formatter was being a little dramatic with the truncation 💀 slay either way, you understood it, and that's what matters 💖✨🎀
