💅 usb_kill_anchored_urbs(9) 💅

okay bestie, welcome to the Kernel API Manual page for usb_kill_anchored_urbs — yeah it's a mouthful, we're gonna get through it together 🫶

---

🌸 NAME 🌸

usb_kill_anchored_urbs — literally kills all the URBs that are attached to an anchor. every single one. no survivors. periodt 💀

---

✨ SYNOPSIS ✨

void usb_kill_anchored_urbs (struct usb_anchor *anchor );

---

🎀 ARGUMENTS 🎀

• anchor — the anchor that the requests are bound to, i.e. the little container holding all your URBs. that's the one we're clearing out 🧹

---

🔥 DESCRIPTION 🔥

so what does it actually do? it kills all the outstanding URBs, starting from the back of the queue (yes, back-to-front, it's giving reverse order realness 💅), and it guarantees that no completer callbacks will take place from the anchor after this function returns. like, once it's back, the callbacks are done-done. no sneaky late arrivals.

🚨 big warning, pls read: this routine should not be called by a driver after its disconnect method has returned. do not do that. i'm serious. that's a no-no 💀
