bpf_task_release(9)
π bpf_task_release β kernel API manual, but make it cute
okay so real talk, this is bpf_task_release(9) from the kernel API manual, and it's honestly such a short little icon. like it does exactly one thing and it does it flawlessly. no notes. β¨
π NAME π
bpf_task_release β bestie, this is the one that releases the reference acquired on a task. that's it. that's the whole vibe. drop the ref, free the task, move on with your life π
πΈ SYNOPSIS πΈ
__bpf_kfunc void bpf_task_release (struct task_struct *p );
literally just hand it the pointer and it handles the rest. no cap, the signature is right there ^^^
π¦ ARGUMENTS π¦
pβ the task on which a reference is being released. so like, this is thestruct task_struct *you're saying "okay i'm done with you now" to. it's the exact task whose reference is getting dropped. one job, one pointer, zero drama π«Ά
β¨ SEE ALSO β¨
and now the part where the kernel is like "here's my entire friend group, say hi to all of them." the kernel file lives at ./kernel/bpf/helpers.c, and these are all the siblings π

ngl that reference list is giving "tag yourself i'm bpf_strchrnul" energy. every single one of them matters, do not skip π
mwah π that's the whole page. short, sweet, and correct β the holy trinity fr fr.
sign-off time bestie: this one came out of the ./kernel/bpf corner of the source tree, dated October 2026, and it's the bpf_task_release(9) page π go forth and drop your refs responsibly, ily π
