init_worker_pool(9)

📦 version 7.3.1, in nixpkgs unstable

✨ init_worker_pool — kernel API manual, but make it make sense ✨

okay so bestie, welcome to init_worker_pool(9) 💅 this is a kernel API page (section 9, the grown-up driver/kernel side of the manual) and it's lowkey the "wake up babe, new worker_pool just dropped" function. let's get into it 🫶

🌸 NAME 🌸

init_worker_pool — literally just initializes a newly zalloc'd worker_pool ✨

🎀 SYNOPSIS 🎀

int init_worker_pool (struct worker_pool *pool );

that's it. that's the whole vibe check. one pointer, one int back 😌

🦋 ARGUMENTS 🦋

  • pool — the worker_pool you want to initialize. the one. the main character. it should already exist (freshly zalloc'd), and you're handing it over to get its life together 💖

💜 DESCRIPTION 💜

so here's the tea 🍓 you call this bad boy to initialize a newly zalloc'd pool. and because that alone wasn't enough slay, it also allocates pool->attrs for you 👑

ngl, that second part matters — pool->attrs is a whole separate allocation, so this isn't a "just memset it and go" situation. it's a real function doing real work, and you're gonna want to check that return value 😭

🌈 RETURN 🌈

  • 0 on success — periodt, we ate 💅
  • -errno on failure — the classic "something went sideways" signalled as a negative errno value 😭

and here's the genuinely iconic part, bestie, so don't skip it: even on failure, all the fields inside pool proper are initialized 🫶 which means you can call put_unbound_pool on pool safely to release it. no leaks, no undefined nonsense, no "wait should I free it or not" panic spiral. cleanup is always safe. iykyk 🔥

fr fr take the -errno seriously — the call failed, but the object is still in a usable, freeable state. that's the whole contract, don't invent extra ones 🙈

⭐ SEE ALSO ⭐

okay so strap in, because this list is long long, but every single one of these is a real one and we're not skipping a single entry 💀 the source of all this lore is the kernel file ./kernel/workqueue.c — go read it if you want the deep lore 🧚

and that's the whole page, bestie 🧚💖 this one came from the ./kernel source and it's dated October 2026 — so yeah, it's giving future-iconic, and honestly? it ate 👑✨ go forth and initialize responsibly 💅
