sbitmap_queue_get(9)

💅 sbitmap_queue_get(9) 💅

okay bestie, welcome to the Kernel API Manual — this is the page for sbitmap_queue_get, and it's giving “please give me one free bit” energy. 🎀

---

✨ NAME ✨

sbitmap_queue_get — tries to allocate a free bit from a &struct sbitmap_queue. slay. 💖

---

🎀 SYNOPSIS 🎀

int sbitmap_queue_get (struct sbitmap_queue *sbq , unsigned int *cpu );

---

🌸 ARGUMENTS 🌸

• sbq — the bitmap queue you're allocating from, bestie. that's the source of the bits.
• cpu — output parameter; it will contain the CPU we ran on (e.g., to be passed to sbitmap_queue_clear). so it's not input, it's literally the receipt. 🧾✨

---

💖 RETURN 💖

if it works, you get a non-negative allocated bit number. if not, you get -1. that's the whole vibe check. 😭👑
