print_next_b...node_ilocked(9)

✨ NAME ✨

okay so bestie, this is the Kernel API Manual page for print_next_b...node_ilocked(9) — the function itself is print_next_binder_node_ilocked, and it does one iconic thing: Print binder_node from a locked list. Periodt. 💅

🌸 SYNOPSIS 🌸

struct binder_node * print_next_binder_node_ilocked (struct seq_file *m
, struct binder_proc *proc , struct binder_node *node , struct
binder_node *prev_node , bool hash_ptrs );

🎀 ARGUMENTS 🎀

• m — the struct seq_file you’re writing output into via seq_printf. 💖
• proc — the struct binder_proc we hold the inner_proc_lock to (if any).
• node — the struct binder_node to print fields of.
• prev_node — the struct binder_node we hold a temporary reference to (if any).
• hash_ptrs — whether to hash the node’s binder_uintptr_t fields.

🦋 DESCRIPTION 🦋

This is the helper function that handles the synchronization around printing a struct binder_node while iterating through proc->nodes or the dead nodes list. It’s giving “lock-aware printing internals” and we respect it. ✨

Lock vibe check: the caller must be holding either proc->inner_lock (for live nodes) or binder_dead_nodes_lock.

That lock is released during the body of this function, but it is reacquired before returning to the caller. So yes, it lets go for a sec and then grabs it right back — no cap. 🔥

💖 RETURN 💖

A pointer to the struct binder_node we hold a tmpref on. That’s the whole return vibe. 🫶
