bitmap_zalloc(9)

💖 bitmap_zalloc 💖

okay so bestie, we're diving into the Kernel API Manual today and this one is short but iconic. it's giving "tiny function, big responsibility" and honestly? we love her for it. ✨

---

✨ NAME ✨

bitmap_zalloc — literally just Allocate bitmap. that's the whole vibe. she allocates a bitmap and she does it fabulously 💅

---

🦋 SYNOPSIS 🦋

unsigned long * bitmap_zalloc (int nbits );

no cap, that's the entire signature. copy it exactly, don't get creative, the compiler WILL notice 🔥

---

🌸 ARGUMENTS 🌸

• nbits — the Number of bits. like, how many bits do you want, bestie? that's the question. you tell her nbits and she knows what to do. periodt. 🎀

ngl there's only one argument here so if you were bracing for a long list... not today. she's lowkey minimalist. main character energy but make it concise. 💀

---

👑 SEE ALSO 👑

• Kernel file ./tools/include/linux/bitmap.h — yes, the header, go read it, iykyk 📖
• bitmap_and(9) — her friend! the bitwise AND one! go say hi 🫶

---

and that's the whole page, bestie — short, sweet, and absolutely ate. 💖 no bugs, no exit statuses, no environment variables, she's just a clean little allocation function living her truth. 🌈

sign-off time: this little beauty comes from ./tools/include/linux and the page is dated October 2026 — and the header/footer both say bitmap_zalloc(9) because she's consistent like that. 💜🎀💅
