rio_clear_locks(9)

🌸 rio_clear_locks — the kernel API manual, bestie edition 🌸

okay so we're in the <pink>rio_clear_locks(9)</pink> page of the Kernel API Manual, and honestly? this one's a little cleanup queen. let's get into it 💅

---

✨ NAME ✨

rio_clear_locks — releases, like, all the host locks and signals that enumeration is complete 🎀

---

🦋 SYNOPSIS 🦋

int rio_clear_locks (struct rio_net *net );

---

💖 ARGUMENTS 💖

• net — the RIO network we're running on. that's the one. the main character. 🌟

---

🔥 DESCRIPTION 🔥

okay so here's the vibe: it marks the component tag CSR on each device with the enumeration complete flag. yes, every single one, no skipping, we're doing the whole roster 💅

once that's done — when it's complete — it then releases the host locks on each device. locks: released. hands: washed. no cap. 🧼✨

return value check, because we always check:

• returns 0 on success 🎉
• returns -EINVAL on failure 😭

💀 friendly reminder that -EINVAL is the failure signal here — if you see that, something went sideways and it's not a vibe.
