ioc_lookup_icq(9)

✨ ioc_lookup_icq 💅

okay bestie, welcome to the Kernel API Manual page for ioc_lookup_icq — which lives in section 9 of the manual, iykyk 🎀

🌸 NAME 🌸

ioc_lookup_icq — lookup io_cq from ioc in the io issue path

🦋 SYNOPSIS 🦋

struct io_cq * ioc_lookup_icq (struct request_queue *q );

✨ ARGUMENTS ✨

• q — the associated request_queue 👑

💖 DESCRIPTION 💖

So basically: this one looks up the io_cq associated with the ioc–q pair, from ioc. 🫶

It must be called from the io issue path. And it'll either return NULL if it's the first time the current issue io is going to q, or it returns a valid icq. No in-between, periodt. 💅

🔥 SEE ALSO 🔥

Kernel file ./block/blk-ioc.c, plus these iconic siblings:

• get_io_context(9)
• ioc_clear_queue(9)
• put_io_context(9)

and that's the whole page, bestie — go slay some io_cq lookups 🧚💜

ok so the source is ./block, the version/date is October 2026, and it's all filed under ioc_lookup_icq(9) — mwah, bye! 💋🎀
