STRUCT SSAM_NOTIFIER_BLOCK(9)

💖 NAME 💖

okay bestie, welcome to the struct ssam_notifier_block(9) page from the Kernel API Manual — yes, that manual. This struct is literally the base notifier block for SSAM event notifications. It's giving foundational, and we're obsessed. ✨

🌸 SYNOPSIS 🌸

Here's the exact shape of it, no edits, no cap:

       struct ssam_notifier_block {
           struct list_head node;
           ssam_notifier_fn_t fn;
           int priority;
        };

👑 Members 👑

• node — the node for the list of notifiers. Yes bestie, it's the list-link member. 🫶
• fn — the callback function of this notifier. This function takes the respective notifier block and event as input and should return a notifier value. That notifier value can either be obtained from the flags provided in enum ssam_notif_flags, converted from a standard error value via ssam_notifier_from_errno, or a combination of both (e.g. ssam_notifier_from_errno(e) | SSAM_NOTIF_HANDLED). Iconic callback behavior, honestly. 💅
• priority — priority value determining the order in which notifier callbacks will be called. A higher value means higher priority, i.e. the associated callback will be executed earlier than other (lower priority) callbacks. So yes, bigger number = earlier callback, periodt. 🔥

mwah 💅 this cutie came from ./include/linux/surface_aggreg..., dated October 2026, and it's the struct ssam_notifier_block(9) page. Bye bestie, go slay those notifiers! 🫶🌈
