hid_device_io_stop(9)

💅 hid_device_io_stop(9) — the Kernel API Manual moment 🎀

okay bestie, so this one lives in the Kernel API Manual and it's lowkey a little two-line function with a LOT of rules, so pay attention 💖

---

✨ NAME ✨

hid_device_io_stop — disable HID input during probe, remove

bestie the name literally tells you everything: we're stopping the HID input flow, and the window where that matters is probe and remove 🫶

---

🌸 SYNOPSIS 🌸

void hid_device_io_stop (struct hid_device *hid );

that's it. no return value, no drama, void and done 💅

---

🦋 ARGUMENTS 🦋

• hid — the device. that's the whole description. it's the HID device, she's the main character, hand her over 😌

---

👑 DESCRIPTION 👑

so here's the vibe check 🔥 — you should only call this after hid_device_io_start. like, start first, stop second, that's the order, no cap.

what it does: it will prevent incoming packets from going to the driver for the duration of probe, remove. so during that probe/remove window, packets are just... not invited to the driver party 🙈

and here's the detail that trips people up (iykyk): if called during probe, packets will still go to the driver after probe is complete. so it's not a forever-block, it's a "not right now" block ✨

⚠️ final rule, and it's a big one: this function should only be called by the thread calling probe or remove. not your random other thread. not your friend's thread. the probe/remove thread. periodt 💀
