for_each_of_graph_port(9)

💅 NAME 💅

okay so bestie, this is the manual page for for_each_of_graph_port(9) — straight from the Kernel API Manual — and it's here to help you iterate over every port in a device or ports node. periodt. ✨

🦋 SYNOPSIS 🦋

for_each_of_graph_port (parent , child );

🎀 ARGUMENTS 🎀

• parent — the parent device or ports node containing the port. it's giving "where the ports live" energy 🫶
• child — the loop variable pointing to the current port node. main character of every loop pass, honestly 👑

🔥 DESCRIPTION 🔥

So here's the tea ☕: when you break out of the loop, and you're still gonna keep using child, you need to use return_ptr(child) or no_free_ptr(child) so that __free is not called for it. no cap, this is the important bit — don't let the cleanup vibe free something you still need, bestie 😭💀

when you break out and keep using child, use return_ptr(child) or no_free_ptr(child) so you don't call __free for it. 🚨

mwah 💋 — this iconic little page comes from source/version ./include/linux, dated October 2026, and it's literally the for_each_of_graph_port(9) manual. bye bestie, go slay those ports 🎀✨🦋
