💅 seq_buf_do_printk — Kernel API Manual

okay so bestie, welcome to the seq_buf_do_printk(9) page, straight out of the Kernel API Manual ✨ this one is literally so cute and tiny, you're gonna eat it up.

---

🌸 NAME 🌸

seq_buf_do_printk — it does printk() on a seq_buf, line by line 🎀 no cap.

---

✨ SYNOPSIS ✨

void seq_buf_do_printk (struct seq_buf *s , const char *lvl );

like, that's the whole vibe. two args, zero drama 🫶

---

🦋 ARGUMENTS 🦋

• s — the seq_buf descriptor 💖 this is your buffer, your main character.
• lvl — the printk level 👑 aka how loud we're being about it.

---

💜 DESCRIPTION 💜

So the way this works: it printk-s a multi-line sequential buffer, line by line 🌈 one line at a time, iconic behaviour honestly.

And before it does any of that, the function makes sure that the buffer in s is NUL-terminated and safe to read as a string 🧚✨ so like, no reading past the end, no cursed garbage, we stay safe out here. periodt.
