llist_del_first_init(9)

💅 llist_del_first_init — a love letter to lock-less lists

okay so this is a page from the Kernel API Manual, section 9, and the star of the show is llist_del_first_init. she pops the first entry off a lock-less list and leaves it looking fresh and unlisted. bestie, it's giving "delete but make it clean" ✨

---

✨ SYNOPSIS ✨

struct llist_node * llist_del_first_init (struct llist_head *head );

that's it. that's the whole vibe. 🎀

---

🌸 ARGUMENTS 🌸

• head — the head of the lock-less list you wanna delete from. your main character pointer, basically. 👑

---

🦋 DESCRIPTION 🦋

so this function behaves the same as llist_del_first, except — and this is the iconic part — llist_init_node gets called on the returned node. the way that works means llist_on_list will report false for that node. literally off the list. not on it. marked as being off-list. slay. 💅

no cap, that's the entire difference. same deletion energy, but the node comes back already de-listed and ready to be reused without any "wait, am i still on a list?" confusion. 🧚

⭐ bye bestie ⭐

that's the whole page! 💖 this little gem lives over in ./include/linux and the version stamped on it is October 2026 — so yeah, future-dated and still iconic. mwah. 🌈🍓
