STRUCT SSAM_NF_HEAD(9)

🌸 struct ssam_nf_head(9) 🌸

okay bestie, so this is a page straight out of the Kernel API Manual and it's all about struct ssam_nf_head — literally the notifier head for SSAM events. that's it, that's the whole vibe. tiny struct, big main character energy 💅

---

✨ NAME ✨

struct ssam_nf_head — the notifier head for SSAM events, periodt.

---

🦋 SYNOPSIS 🦋

here's the whole glow-up, no cap:

struct ssam_nf_head {
    struct srcu_struct srcu;
    struct list_head head;
 };

like… two members. minimal. iconic. she said "I don't need a big struct, I need a correct struct" 🎀

---

👑 Members 👑

💖 srcu

the struct srcu_struct that handles synchronization for this head. it's giving "I keep everyone in line" energy — she's the responsible friend of the group chat 🌈

💜 head

the struct list_head that acts as the list-head for all the notifier blocks registered under this head. all the notifier blocks literally queue up here like it's a party and head is the door 🫶

and that's the whole page babes ✨ this lil' struct lives in ./drivers/platform/surface/agg... and this particular telling is dated October 2026 — so go forth, register those notifier blocks, and slay 💅💖🦋
