💖 iopf_queue_discard_partial(9) 💖

okay bestie, this page is straight from the Kernel API Manual, and it’s short, sweet, and lowkey important. Let’s get into it ✨

✨ NAME ✨

iopf_queue_discard_partial — Remove all pending partial fault 💅

---

🎀 SYNOPSIS 🎀

int iopf_queue_discard_partial (struct iopf_queue *queue );

---

🦋 ARGUMENTS 🦋

• queue — the queue whose partial faults need to be discarded 🫶

---

🌸 DESCRIPTION 🌸

okay so picture this: the hardware queue overflows 😭 and the last page faults in a group may have been lost. When that happens, the IOMMU driver calls this function to discard all partial faults. Slay, cleanup time 💅

bestie, important: the driver shouldn’t be adding new faults to this queue concurrently. fr fr, don’t do that 🙈

---

🌈 RETURN 🌈

Returns 0 on success and <0 on error. That’s it, that’s the vibe check ✨
