✨ dbg_check_nondata_nodes_order(9) ✨

okay bestie so you're in the Kernel API Manual (dbg_check_n..._nodes_order(9)) and this page is literally just a vibe check for a linked list 🎀 buckle up, it's short and iconic.

---

🌸 NAME 🌸

dbg_check_nondata_nodes_order — check that list of data nodes is sorted.

(no cap, that's what it says, and yes we're keeping it exactly like that 😭)

---

🦋 SYNOPSIS 🦋

int dbg_check_nondata_nodes_order (struct ubifs_info *c , struct
list_head *head );

---

💜 ARGUMENTS 💜

• c — the UBIFS file-system description object, the main character of this whole operation 👑
• head — the list of nodes ('struct ubifs_scan_node' objects). literally the list we're inspecting, periodt 💅

---

✨ DESCRIPTION ✨

so here's the tea 🍓: this function returns zero if the list of non-data nodes is sorted correctly, and -EINVAL if it's not. that's it. that's the whole function. iykyk.

like, it's giving "one job and it does it". if everything's in order you get a happy little 0, and if the ordering is a mess you get -EINVAL and someone's got some explaining to do 😭
