ntb_clear_ctx(9)

💅 ntb_clear_ctx(9) — Kernel API Manual, bestie edition 🎀

okay so picture this: you're deep in the ntb_clear_ctx(9) page of the Kernel API Manual, and honestly? It's giving tiny-but-mighty. Let me put you on. 💖

---

✨ NAME ✨

ntb_clear_ctx — literally just disassociate any driver context from an ntb device. that's the whole vibe. unlink it, un-bind it, send it home. 🦋

---

🌸 SYNOPSIS 🌸

void ntb_clear_ctx (struct ntb_dev *ntb );

yes bestie, it returns void. nothing comes back. it simply does. main character energy for real. 👑

---

🎀 ARGUMENTS 🎀

• ntb — the NTB device context. this is the device we're breaking up with. 💔

---

💜 DESCRIPTION 💜

So here's the tea: ntb_clear_ctx() clears any association that may exist between a driver context and the ntb device. that's it. that's the function.

notice the "may exist"? yeah — it's chill like that. if there's a link between your driver context and the device, it's gone now. consider it ✨ severed ✨. ngl it's the cleanest little teardown arc and I'm obsessed. 🫶

no cap, this is the one you call when you want that driver context out of the device's business. periodt. 💅
