So this is a page from the Kernel API Manual (section 9, the kernel-API girlies 🧚) and it's about bpf_wakeup_sources_get_head. Yes, that's a mouthful. No, we're not abbreviating it. It's iconic, let her have her full name ✨

🌸 NAME 🌸

bpf_wakeup_sources_get_head — literally just gets you the head of the wakeup sources list. That's it. That's the whole job. She's a one-trick pony and she ate 💅

⭐ SYNOPSIS ⭐

__bpf_kfunc void * bpf_wakeup_sources_get_head (void );

Look at her. No arguments, takes no notes, asks no questions. Returns a void * and it's a __bpf_kfunc, so she lives in BPF-kfunc land 🦋

🎀 ARGUMENTS 🎀

  • void — no arguments, bestie. Nothing. Zero. The void is voiding. She needs nothing from you and honestly? Respect 🙈

🔥 RETURN 🔥
