sbitmap_show(9)

✨ sbitmap_show — kernel API manual ✨

okay so bestie, you know how sbitmap_show(9) is the page? yeah. this is that. we're in the Kernel API Manual, and it's lowkey a little diagnostic icon. let's get into it 💅

---

🌸 NAME 🌸

sbitmap_show — dumps the info from a &struct sbitmap straight into a &struct seq_file. that's the whole job. she's a reporter, not a hero 🎀

---

⭐ SYNOPSIS ⭐

void sbitmap_show (struct sbitmap *sb , struct seq_file *m );

returns nothing (it's void, she's just here to say things, not to give you a value), takes your bitmap, takes your seq_file. done. periodt 💖

---

🦋 ARGUMENTS 🦋

• sb — the bitmap to show. this is the star of the show, the main character, the thing you're dumping 🌈
• m — the struct seq_file this gets written to. it's the notepad, she's the one holding the pen 🫶

---

👑 DESCRIPTION 👑

so this whole thing is for debugging. that's the vibe check. it's not a stable public API you should build your whole lil architecture on, okay?

⚠️ heads up, bestie: the format may change at any time. no cap. so if you're parsing this output in a script and expecting it to stay the same forever… 😭 don't. it's giving "undefined behaviour but for text". it's for eyeballs, not for parsers 💀
