kmalloc_array(9)

💖 kmalloc_array(9) — kernel API manual, bestie edition 💖

Okay so real talk: this is the kernel API manual page for kmalloc_array, and it's genuinely one of the most useful little guys in the whole slab family. Buckle up 🎀

✨ NAME ✨

kmalloc_array — allocate memory for an array. That's it, that's the whole vibe. It grabs you a chunk of memory sized for n things of size bytes each. Slay. 💅

🌸 SYNOPSIS 🌸

void * kmalloc_array (size_t n , size_t size , gfp_t flags );

Look at her. Three args, returns a void *, no drama. 🦋

🧚 ARGUMENTS 🧚

• n — number of elements. Like, how many of the thing do you want? Count them. No cap. ⭐
• size — element size. How big is one of those things? That's this one. 🍓
• flags — the type of memory to allocate (see kmalloc). Yes bestie, it's giving "go read the kmalloc page for the actual flag list" — this one's just pointing you there, iykyk. 👑

Heads up: flags is documented by reference to kmalloc, so if you need the actual flag names and semantics, that's where you go. Don't @ me, @ kmalloc. 😭
