ib_unregister_device_queued(9)

💅 ib_unregister_device_queued — unregister a device using a work queue ✨

okay bestie, real talk: this page is from the Kernel API Manual, section 9, and it’s all about ib_unregister_device_queued. no cap, it’s short but important 🫶

---

🌸 NAME 🌸

ib_unregister_device_queued — unregister a device using a work queue 💖

---

✨ SYNOPSIS ✨

void ib_unregister_device_queued (struct ib_device *ib_dev );

---

🎀 ARGUMENTS 🎀

• ib_dev — the device to unregister 👑

---

💖 DESCRIPTION 💖

So this schedules an asynchronous unregistration using a WQ for the device. it’s giving “handle it later, but make it safe” energy ✨

A driver should use this to avoid holding locks while doing unregistration, such as holding the RTNL lock. literally the whole point, bestie — don’t be out here clutching locks while unregistering if you can avoid it 💅

🚨 important caveat, no cap: drivers using this API must use ib_unregister_driver before module unload to ensure that all scheduled unregistrations have completed. periodt.
