klist_init(9)

💅 klist_init(9) — from the Kernel API Manual, bestie

Okay so we're diving into the kernel API manual today and honestly? This one is a little gem. It's klist_init(9), and yeah it's a kernel function, but don't panic — it's literally just "set up your klist, girl." We got this. 🫶

✨ NAME ✨

klist_init — Initialize a klist structure.

Like, that's it. That's the whole job. It initializes a klist structure. Slay. 💅

🌸 SYNOPSIS 🌸

void klist_init (struct klist *k , void (*get)(struct klist_node *) ,
       void (*put)(struct klist_node *) );

No cap, that's the exact signature — copy it character for character, bestie, don't get creative with it. 🙈

🎀 ARGUMENTS 🎀

  • k — The klist we're initializing. This is the main character right here, the whole reason we're gathered. 👑
  • get — The get function for the embedding object, or NULL if there isn't one. Lowkey optional, highkey important when you need it.
  • put — The put function for the embedding object, or NULL if there isn't one. Same vibe as get, just the release-y counterpart. 🦋

💖 DESCRIPTION 💖

So here's the tea: klist_init initialises the klist structure. Simple enough, right?

But here's where it gets good — if the klist_node structures are going to be embedded in refcounted objects (and that's necessary for safe deletion, fyi, not a nice-to-have), then the get and put arguments get used to initialise functions that take and release references on those embedding objects. It's giving teamwork. It's giving lifecycle management. It's giving "we take refs so we don't blow up later." 🔥

Ngl, that "necessary for safe deletion" bit is doing a lot of heavy lifting — don't sleep on it. 😭

Kernel file ./lib/klist.c — and the whole klist friend group, fr fr:

They're all in their little ./lib era together and honestly? Obsessed. 💜

⭐ That's the whole page, bestie — go init yourself a klist and live your main character life. This one came from ./lib, dated October 2026, and no I will not be normal about it. 🧚💖
