💅 ddcb_cmd_cleanup(9) — like, the Kernel API Manual page, bestie

okay so we're in the Kernel API Manual today and the star of the show is ddcb_cmd_cleanup — section 9, obviously, we stay in our lane. She's a little cleanup queen and honestly? we love a function that knows how to tidy up. 🧹✨

🎀 NAME 🎀

ddcb_cmd_cleanup — the one that removes dynamically created fixup entries. no cap, that's the whole job. 💅

---

✨ SYNOPSIS ✨

int ddcb_cmd_cleanup (struct genwqe_file *cfile , struct ddcb_requ *req
);

she returns an int and takes exactly two args, that's the vibe check and she passed 🫶

🌸 ARGUMENTS 🌸

• cfile — descriptor of the opened file, aka which file we're talking about, hello 👋
• req — the DDCB work request, like the actual thing we're cleaning up after 💖

🦋 DESCRIPTION 🦋

so basically she removes those dynamically created fixup entries — but only if there are any, okay? she's not out here doing work for nothing, main character energy only. 😭

and the important bit, listen up: pinnings are not removed. nope. not her department. don't come for her about the pinnings, she did not sign up for that. 💀
