ring_buffer_iter_reset(9)

💫 ring_buffer_iter_reset(9) 💫

okay so this is a page from the Kernel API Manual, bestie — yes, that kernel, the big one 👑 — and it's all about one tiny lil function that does one tiny lil thing. and honestly? it ate. 🎀

---

✨ NAME ✨

ring_buffer_iter_reset — reset an iterator, that's it, that's the whole vibe 🦋

---

✨ SYNOPSIS ✨

void ring_buffer_iter_reset (struct ring_buffer_iter *iter );

like… it returns void. it gives nothing back. no notes, no receipts, just pure action. main character energy fr 💅

---

✨ ARGUMENTS ✨

• iter — the iterator you wanna reset 🫶 literally just hand it over and it gets a fresh start. glow-up era.

---

✨ DESCRIPTION ✨

So here's the tea ☕ — this bad boy resets the iterator, so that it will start from the beginning again. that's it!! a full rewind, no cap 🌈 it's giving "new year, new me" but for a struct ring_buffer_iter *.

ngl, sometimes you just need to go back to the start, and this function is right there for you. iconic behavior honestly 😭💖

ok tiny warning-ish thing from your girl: that SEE ALSO list is LONG long. like, scroll-for-a-while long. don't panic, it's just the whole ring buffer family showing up to the group chat at once 💀💖

and that's the whole page!! mwah 💋 ok bye bestie — this one came from ./kernel/trace, dated October 2026, and it's ring_buffer_iter_reset(9) signing off 🫶🌸⭐
