sbitmap_for_each_set(9)

✨ sbitmap_for_each_set(9) ✨

okay so this is a page from the Kernel API Manual, and today's main character is sbitmap_for_each_set 💅

🌸 NAME 🌸

sbitmap_for_each_set — iterate over each set bit in a &struct sbitmap. that's it, that's the whole vibe 🎀

🦋 SYNOPSIS 🦋

void sbitmap_for_each_set (struct sbitmap *sb , sb_for_each_fn fn , void
       *data );

💖 ARGUMENTS 💖

• sb — the bitmap bestie is iterating over. this is the one you're walking through 🚶‍♀️
• fn — the callback. it should return true to keep going, or false to break early and dip out 😭 (iykyk, it's giving "graceful exit")
• data — a pointer that gets passed straight to your callback. hand it whatever you want fr fr 🫶

so anyway, the source for all this is ./include/linux, dated October 2026, and it's filed under sbitmap_for_each_set(9) — stan the kernel docs bestie, they literally never miss ✨🫶
