sbitmap_queue_init_node(9)

📦 version 7.3.1, in nixpkgs unstable

💅 sbitmap_queue_init_node ✨

okay so this is the sbitmap_queue_init_node(9) page from the Kernel API Manual, and bestie, it's literally the "set up your bitmap queue on a specific memory node" function. it's giving constructor energy. let's get into it 🎀

🌸 NAME 🌸

sbitmap_queue_init_node — initializes a &struct sbitmap_queue on a specific memory node. that's it. that's the whole vibe. ✨

🦋 SYNOPSIS 🦋

int sbitmap_queue_init_node (struct sbitmap_queue *sbq , unsigned int
depth , int shift , bool round_robin , gfp_t flags , int node );

the way that signature just goes on — six arguments, no cap. 🔥

💖 ARGUMENTS 💖

  • sbq — the bitmap queue you're initializing. main character. the one getting set up. 👑
  • depth — no thoughts, just "see sbitmap_init_node". it's a delegation moment, iykyk. 🫶
  • shift — same deal, "see sbitmap_init_node". the docs said go read that one, and honestly? valid. 💅
  • round_robin — "see sbitmap_get" — this one controls the round-robin behaviour over there. go look at sbitmap_get for the tea. ☕
  • flags — allocation flags. the gfp vibes, basically. 🌈
  • node — the memory node you're allocating on. pick your fave. 📍

⭐ RETURN ⭐

returns Zero on success, or a negative errno on failure. that's the whole story, fr fr. zero = slay, negative errno = not slay 😭

🧚 SEE ALSO 🧚

okay this list is long and honestly iconic, so buckle up bestie, we're going through all of them 💜

Kernel file ./include/linux/sbitmap.h and friends:

like, the whole sbitmap family reunion 🫶 no crumbs left.

and that's the page!! 🎀✨

cute little sign-off for the credits: this one lives in ./include/linux and the manual's dated October 2026 — so yeah, future energy, we love to see it. bye bestie, go init that queue responsibly 💖🦋💅
