__vmalloc_array(9)

✨ __vmalloc_array(9) ✨

ok bestie, welcome to the Kernel API Manual 💅 this one's short and sweet — it's __vmalloc_array, and it is literally the moment when you need a whole array of stuff to live in memory that's virtually contiguous 🦋

🎀 NAME 🎀

__vmalloc_array — allocate memory for a virtually contiguous array. that's it. that's the whole vibe. ✨

🌸 SYNOPSIS 🌸

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

💖 ARGUMENTS 💖

• n — number of elements. how many lil guys are we fitting in here 👑
• size — element size. how chunky each one is 🍓
• flags — the type of memory to allocate (see kmalloc). yes, the flags go straight to kmalloc's docs, iykyk 🙈
