mem_cgroup_sk_charge(9)

💖 mem_cgroup_sk_charge — socket-memory charging, bestie 💖

okay so welcome to the mem_cgroup_sk_charge(9) page from the Kernel API Manual — this is the lil function that handles charging socket memory, and yes it's giving kernel-internals main character energy. 🫶

---

✨ NAME ✨

mem_cgroup_sk_charge — charge socket memory. That's the whole vibe: socket memory gets charged. 💅

---

🦋 SYNOPSIS 🦋

bool mem_cgroup_sk_charge (const struct sock *sk , unsigned int nr_pages
, gfp_t gfp_mask );

---

🎀 ARGUMENTS 🎀

• sk — socket in memcg to charge. This is the socket getting its memcg moment. ✨
• nr_pages — number of pages to charge. Literally the page count, no cap.
• gfp_mask — reclaim mode. Keep it exactly as reclaim mode, bestie.

---

💅 DESCRIPTION 💅

Charges nr_pages to memcg. Then it returns true if the charge fit within memcg's configured limit, and false if it doesn't. That's the tea. 🍓
