💅 edac_scrub_get_desc(9) — Kernel API Manual ✨

okay so bestie, welcome to the edac_scrub_get_desc(9) page — yes it's a real kernel API manual page, no I'm not kidding, and yes we're gonna get through it together 🫶

---

🌸 NAME 🌸

edac_scrub_get_desc — the function that gets you your EDAC scrub descriptors. that's literally it. that's the whole vibe. it's giving "fetch the descriptor" energy and honestly? iconic 👑

---

🎀 SYNOPSIS 🎀

int edac_scrub_get_desc (struct device *scrub_dev , const struct
       attribute_group **attr_groups , u8 instance );

so it hands back an int (keep an eye on that, it's the receipts later), and it takes three things — a struct device * called scrub_dev, a const struct attribute_group ** called attr_groups, and a u8 called instance. put some respect on that u8, it's doing its best 💜

---

🦋 ARGUMENTS 🦋

• scrub_dev — the client device, the one that actually has scrub support. this is the main character of the argument list ngl ✨
• attr_groups — a pointer to the attribute group container. it's the container. it holds the attribute groups. we love a container 💅
• instance — the device's scrub instance number. like a little name tag but make it a number 🎀

---

🔥 RETURN 🔥

here's where the drama lives, bestie — this is what you get back:

• 0 — Success. we ate. 💖
• -EINVAL — Invalid parameters passed. something you handed over was Not It 🙈
• -ENOMEM — Dynamic memory allocation failed. the memory said "no <3" 😭

fr fr check that return value. 0 is the slay, the negatives are the "go fix your arguments or free some memory" vibes. no cap.
