list_lru_del_obj(9)

okay so bestie, welcome to the list_lru_del_obj(9) page from the Kernel API Manual 💅 this is the one where we delete an element from the lru list, and it’s lowkey iconic. let’s get into it.

✨ NAME ✨

list_lru_del_obj — delete an element from the lru list.

---

🎀 SYNOPSIS 🎀

bool list_lru_del_obj (struct list_lru *lru , struct list_head *item );

---

💖 ARGUMENTS 💖

• lru — the lru pointer. yes bestie, that one.
• item — the item to be deleted. bye girl 👋

---

🦋 DESCRIPTION 🦋

so this function is similar to list_lru_del, but with a little main-character twist: the NUMA node and the memcg of the sublist are determined by the item list_head. the way that works is very “trust the list_head, it knows the vibe” ✨

and this assumption is valid for slab objects LRU such as dentries, inodes, etc. no cap, that’s the whole situation.

---

🌈 RETURN 🌈

true if the list was updated, false otherwise. that’s it, that’s the return, periodt 💅
