💅 bpf_task_wo...edule_signal(9) — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual entry for bpf_task_wo...edule_signal(9) (yes the name got truncated by the terminal, no that's not a typo on my end, that's just how it's printed 😭). it's giving very niche, very powerful, very "iykyk" energy. let's get into it 🎀

✨ NAME ✨

bpf_task_work_schedule_signal — schedules a BPF callback using task_work_add with TWA_SIGNAL mode 🦋

🌸 SYNOPSIS 🌸

__bpf_kfunc int bpf_task_work_schedule_signal (struct task_struct *task
, struct bpf_task_work *tw , void *map__const_map ,
bpf_task_work_callback_t callback , struct bpf_prog_aux *aux );

💖 ARGUMENTS 💖

  • task — the Task struct for which the callback should be scheduled ✨
  • tw — pointer to struct bpf_task_work inside a BPF map value, used for internal bookkeeping 🧚
  • map__const_map — the bpf_map that embeds struct bpf_task_work in the values 💫
  • callback — pointer to the BPF subprogram to call 🔥
  • aux — pointer to the bpf_prog_aux of the caller BPF program, implicitly set by the verifier 👑

⭐ RETURN ⭐

0 if task work has been scheduled successfully, negative error code otherwise 🫶

ngl bestie, that SEE ALSO list is a whole friend group 😭 do not lose a single one of them, they all matter 💜

okay that's the whole page, periodt 💅 this lil gem lives in ./kernel/bpf and it's dated October 2026 — mwah, go schedule some task work, you absolute icon 👑✨🫶
