blk_unregister_queue(9)

💅 blk_unregister_queue(9)

okay so this is a page from the Kernel API Manual, section 9 — the kernel-functions girlies. and bestie, it's a short one, but it's important, so let's get into it ✨

---

🌸 NAME

blk_unregister_queue — literally the counterpart of blk_register_queue(). that's it. that's the whole vibe. one in, one out, yin and yang, register and unregister, periodt 💖

---

🎀 SYNOPSIS

void blk_unregister_queue (struct gendisk *disk );

no cap, that's the whole signature. copy it exactly, don't get cute with it 🙈

---

🦋 ARGUMENTS

• disk — the struct gendisk * for the disk whose request queue you want unregistered from sysfs. like, you're telling sysfs "she's leaving the group chat" 👋✨

---

⭐ NOTE

read this twice, bestie: the caller is responsible for guaranteeing that this function is called after blk_register_queue has finished. so like... don't call it early. don't call it mid-register. the caller has to make sure the ordering is correct, and if you get it wrong that's on you, not on this function 😭💀

it's giving "you had one job" energy but fr fr, it matters.

---

💜 SEE ALSO

• Kernel file ./block/blk-sysfs.c — go read it, iykyk 🔥
• blk_register_queue(9) — the counterpart, the other half, the main character to this one's love interest 🫶

---

so yeah, that's the whole page 🌈 she's short, she's sweet, she unregisters a request queue from sysfs, and she expects you to have called blk_register_queue first. iconic behaviour, honestly 👑💅

sign-off time 🎀 — this little cutie lives in the kernel source at ./block, it's dated October 2026, and it's brought to you by the Kernel API Manual, section 9. mwah 💋✨
