💅 dbg_check_cats(9)

okay so bestie, welcome to the Kernel API Manual — this one's from the <./fs/ubifs> girlies and it's literally called dbg_check_cats. yes it's about categories. no it's not about your cat. let's go ✨

---

🌸 NAME

dbg_check_cats — check category heaps and lists.

like, the whole vibe of this function is: look at the heaps, look at the lists, make sure nobody's lying. a little audit. a vibe check for data structures, if you will. 👑

---

🎀 SYNOPSIS

int dbg_check_cats (struct ubifs_info *c );

that's it. that's the whole call. she takes one argument and returns an int. minimal queen energy. 💅

---

🦋 ARGUMENTS

• c — UBIFS file-system description object. this is the context babe, the whole entire filesystem’s situation, passed in so the function knows what to check. don't forget her, she's load-bearing. 🫶

---

✨ DESCRIPTION

This function returns 0 on success and a negative error code on failure.

and that's genuinely the whole description, no cap. 0 = we ate, everything's fine. negative number = something is Not It and you should probably care. 😭

real talk: this is a debug checker, so it's doing checking, not fixing. if she hands you a negative error code, that's your cue to go look at the actual problem. 🌈
