kmalloc_objs(9)

💖 kmalloc_objs(9) — Kernel API Manual 💖

okay so bestie, welcome to the kmalloc_objs(9) page — it’s giving “allocate me an array of a type” energy, and honestly? iconic. 🎀

---

✨ NAME ✨

kmalloc_objs — Allocate an array of the given type

like literally, it grabs you an array of whatever type you asked for. no cap. 💅

---

🌸 SYNOPSIS 🌸

kmalloc_objs (VAR_OR_TYPE , COUNT , ... );

---

🦋 ARGUMENTS 🦋

• VAR_OR_TYPE — Variable or type to allocate an array of. yes bestie, that’s the whole vibe: tell it what kind of array you want. ✨
• COUNT — How many elements in the array. how many little guys are we fitting in here? 🔥
• ... — optional GFP flags for the allocation (GFP_KERNEL when not specified). so if you don’t pass anything, it defaults to GFP_KERNEL — periodt. 🌈

---

👑 RETURN 👑

newly allocated pointer to array of VAR_OR_TYPE on success, or NULL on failure.

so on the good path you get a shiny new pointer to your array, and on the bad path you get NULL — not me being dramatic, that’s literally the contract. 😭💀
