alloc_pages_mpol(9)

✨ NAME ✨

alloc_pages_mpol — Allocate pages according to NUMA mempolicy. Welcome to the Kernel API Manual, bestie; this is the alloc_pages_mpol(9) page, and we are absolutely making it make sense 💅✨

🎀 SYNOPSIS 🎀

struct page * alloc_pages_mpol (gfp_t gfp , unsigned int order , struct
mempolicy *pol , pgoff_t ilx , int nid );

💖 ARGUMENTS 💖

• gfp — the GFP flags, aka the flags situation for this allocation ✨
• order — the order of the page allocation. That's the size vibe, bestie 🫶
• pol — pointer to the NUMA mempolicy 👑
• ilx — index for interleave mempolicy — also distinguishes alloc_pages 🦋
• nid — preferred node, usually numa_node_id but mpol may override it 🌸

🔥 RETURN 🔥

The page on success, or NULL if allocation fails. That's it — page or no page, no cap 😭💀
