get_mem_cgroup_from_current(9)

💅 get_mem_cgroup_from_current(9)

okay so bestie, welcome to the Kernel API Manual — yes, that's the manual name, we're in the kernel docs girlie pipeline now 🫶

---

🌸 NAME

get_mem_cgroup_from_current — Obtain a reference on the current task's memcg. That's it, that's the whole vibe: you get a reference on the memcg of whatever task is running right now ✨

---

🎀 SYNOPSIS

struct mem_cgroup * get_mem_cgroup_from_current (void );

Like, literally hand it nothing and it hands you back a struct mem_cgroup * pointing at current's memcg, with a reference on it 👑

---

🦋 ARGUMENTS

• void — no arguments. Zero. None. Not a single parameter, bestie, the function is in its "I need nothing from you" era 🙈

ngl the roster is long but every single one of those is a real cross-reference and if you skip a name the kernel girlies will notice 😭 main character energy means reading them all, periodt 🧚

k bye bestie, this one came from ./mm and it's stamped October 2026 — so like, very demure, very kernel-doc-core of it 💖 ✨ 🎀
