💅 kill_css_sync(9) — bestie edition

okay so real talk, this is a page from the Kernel API Manual and it is short short — like, the kernel devs said "the vibe is self-explanatory" and dipped. but we're gonna cover it anyway because every single crumb matters 🍓

✨ NAME ✨

kill_css_sync — the synchronous half of css teardown 🎀

✨ SYNOPSIS ✨

void kill_css_sync (struct cgroup_subsys_state *css );

that's it. that's the whole signature. no return value, no drama, just vibes and a pointer 💅

✨ ARGUMENTS ✨

  • css — the css being killed 🪦 like yes, that's genuinely the entire description the kernel gave us. the css in question. the one getting destroyed. main character of its own teardown arc.

✨ DESCRIPTION ✨

okay so, lowkey, the description here is literally just:

See cgroup_destroy_locked.

that's the whole thing. no cap. the kernel devs pulled an "iykyk" and pointed you at cgroup_destroy_locked for the actual lore 📖✨ so if you want the real explanation of what's going down during teardown, that's where you go. this function is just the synchronous half of the whole css teardown situation — the patient, waits-its-turn half 🧚

✨ SEE ALSO ✨

bestie. buckle up. this list is long long — it's giving "the kernel file is ./kernel/cgroup/cgroup.c and we're gonna list every single friend it has" 🌈🫶

and where do all these live? kernel file ./kernel/cgroup/cgroup.c — that's the source of truth, go read it if you're feeling brave 🫡

and that's the page!! short, sweet, synchronous 💜 this whole thing came out of the Kernel API Manual, source ./kernel/cgroup, dated October 2026 — so if you're reading this from the future, hi, hope the css teardown went well 🌸 no notes, ate, periodt. 🎀✨
