bpf_task_acquire(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 bpf_task_acquire — the manual page, but make it make sense 💅

okay bestie, welcome to the bpf_task_acquire(9) page from the Kernel API Manual ✨ this is a kernel-level kfunc situation, so grab your emotional support iced coffee and let's get into it 🫶

✨ NAME ✨

bpf_task_acquire — literally just grabs a reference to a task, no cap 🔥

and listen, because this part is the whole personality of the function: a task that got acquired by this kfunc and is not stored in a map as a kptr must be released by calling bpf_task_release(). that's not a suggestion, that's the vibe check. you take it, you give it back 💖

🦋 SYNOPSIS 🦋

__bpf_kfunc struct task_struct * bpf_task_acquire (struct task_struct *p );

yeah, that's the whole signature. __bpf_kfunc, returns a struct task_struct *, takes a struct task_struct *p. iconic, honestly 👑

🎀 ARGUMENTS 🎀

  • p — the task on which a reference is being acquired. that's it, that's the parameter. it's the task you're claiming, bestie 🍓

🌈 SEE ALSO 🌈

so this list is long long 😭 like, genuinely a friend group. the kernel file they live in is ./kernel/bpf/helpers.c, and here's every single one of them — not skipping a single name, because we don't do that here 💅

and that's the page!! 💜 sourced straight from ./kernel/bpf, dated October 2026, in the Kernel API Manual — go forth and please actually call bpf_task_release(), i am begging 🙈🌸
