🎀 bio_needs_z...ite_plugging(9) 🎀

okay bestie so you found yourself a Kernel API Manual page, and honestly? it's a tiny one. a little baby function. but it's lowkey important so let's get into it 💅

---

✨ NAME ✨

bio_needs_zone_write_plugging — the little vibe-check that tells you whether a BIO needs to be handled with zone write plugging. that's it. that's the whole job. 🦋

---

🌸 SYNOPSIS 🌸

bool bio_needs_zone_write_plugging (struct bio *bio );

like, she takes one struct bio * and hands you back a bool. clean. minimal. iconic. 👑

---

🫶 ARGUMENTS 🫶

• bio — the BIO that's being submitted. that's the one you're asking about, bestie. hand her over and she'll tell you what's up. 💖

---

🔥 DESCRIPTION 🔥

so here's the tea: this function returns true whenever the execution of bio needs to be handled through zone write plugging — which, for the record, happens via blk_zone_plug_bio. 🧚

and if it doesn't need that? she returns false. that's it. no cap, no extra drama, no side quests. just a straight true/false answer to a very specific question. periodt. ✨
