sbitmap_any_bit_set(9)

✨ sbitmap_any_bit_set ✨

okay bestie, so this is a page from the Kernel API Manual and it's about one (1) very specific little function, and honestly? she's giving "small but crucial" 💅

---

🌸 NAME 🌸

sbitmap_any_bit_set — the vibe check for a &struct sbitmap: is any bit in there set or not? 🔍

---

🎀 SYNOPSIS 🎀

bool sbitmap_any_bit_set (const struct sbitmap *sb );

literally that's the whole signature, no cap. she takes one pointer and hands you back a bool. iconic.

---

🦋 ARGUMENTS 🦋

• sb — the bitmap you want to check. that's it. that's the whole argument. go off queen 🫶

---

⭐ RETURN ⭐

returns true if any bit in the bitmap is set, and false otherwise. simple as that, fr fr 💖

quick note bestie: this page calls sb a "Bitmap to check" — that's the whole spec, don't go reading extra behaviour into it 🙈

mwah 💋 this little page lives in ./include/linux, dated October 2026, and it's part of the Kernel API Manual — so go forth, check those bits, and slay ✨🌈🎀
