lc_del(9)

💖 lc_del(9) — the kernel API manual, bestie edition 💖

okay so you're here for lc_del(9), which lives in the Kernel API Manual (section 9, kernel-land, very main character of it). Let's get into it ✨

---

🌸 NAME 🌸

lc_del — literally just removes an element from the cache. that's the whole gig 🎀

---

✨ SYNOPSIS ✨

void lc_del (struct lru_cache *lc , struct lc_element *e );

---

🦋 ARGUMENTS 🦋

• lc — the lru_cache object. the cache in question, the vibe container 💅
• e — the element to remove. the one getting evicted, no cap 🫶

---

🔥 DESCRIPTION 🔥

so here's the tea: e must be unused (refcnt == 0). that's a hard requirement, not a suggestion, ngl 🙈

what it does, in order:

• moves e from the "lru" list to the "free" list
• sets e->enr to LC_FREE

that's it. that's the whole function. iconic efficiency ⭐

⚠️ fr fr remember: e must be unused — refcnt == 0. don't come at it with a live element 😭
