ioc_create_icq(9)

💅 ioc_create_icq — like, the kernel API manual page, bestie 🎀

okay so this is ioc_create_icq(9) from the Kernel API Manual, and it's lowkey one of those tiny functions that does a whole lot of heavy lifting. buckle up 🦋

---

✨ NAME ✨

ioc_create_icq — create and link io_cq 💖

---

🌸 SYNOPSIS 🌸

struct io_cq * ioc_create_icq (struct request_queue *q );

literally the whole signature, no cap 🔥

---

🧚 ARGUMENTS 🧚

• q — the request_queue of interest 👀 like, the queue you're curious about, that's the one

---

💜 DESCRIPTION 💜

So the vibe here is: make sure the io_cq that links ioc and q actually exists. that's the whole mission 🫶

If that icq doesn't exist yet? no stress — they will be created using gfp_mask. ✨ (yes, gfp_mask gets mentioned here even though it's not in the arg list — that's just how it is, iykyk 🙈)

⚠️ okay important part, pay attention bestie: the caller is responsible for making sure ioc won't go away, and that q is alive and stays alive until this function returns. that's on you, not on the function. main character responsibility energy 👑
