okay bestie, welcome to the Kernel API Manual — yes we're literally in the kernel now, keep up 🫶

✨ NAME ✨

🌸 SYNOPSIS 🌸

void sbitmap_free (struct sbitmap *sb );

like… that's it. one function. one pointer. she's simple and she slays ✨

💀 reminder bestie: this is the free one. if you're still holding onto anything from that bitmap after this, that's on you and it's giving use-after-free energy. free her once and then let her rest 🙈

and that's the whole vibe check, i love this for us 🧚

this little masterpiece lives in ./include/linux, dropped October 2026, and it's filed under sbitmap_free(9) — mwah, bye bestie, go free some memory 💜🍓
