🌸 cgroup_migrate_finish(9) 🌸

okay so bestie, welcome to the Kernel API Manual ✨ — today's main character is cgroup_migrate_finish(9), and honestly? she's the clean-up queen. the "we're done here, tidy up" moment. the one who turns the lights off after the party 🎀

✨ NAME ✨

cgroup_migrate_finish — cleanup after attach 💅

so like, you did the whole migration thing, and now somebody's gotta do the dishes. that's her. that's the job. no cap.

🦋 SYNOPSIS 🦋

void cgroup_migrate_finish (struct cgroup_mgctx *mgctx );

returns void, so no "did it work" report card — she just does the thing and dips 😌

🎀 ARGUMENTS 🎀

  • mgctx — the migration context 💖 like, the lil bag of holding that carries everything about the migration you just did. she needs it to know what to undo.

💜 DESCRIPTION 💜

okay so here's the tea: cgroup_migrate_finish undoes cgroup_migrate_add_src and cgroup_migrate_prepare_dst. that's it, that's the whole vibe — she's the reverse button 🔁

and if you're sitting there like "wait, what did those two even do tho" — the manpage is literally telling you to go read those functions for the details, bestie. it's giving "read the room, read the source." iykyk 📖✨

lowkey important: she's cleanup, not magic. the source page says the specifics live in cgroup_migrate_add_src and cgroup_migrate_prepare_dst, so don't come for her for the fine print 🙈

🌈 SEE ALSO 🌈

the kernel file in question is ./kernel/cgroup/cgroup.c — that's the neighborhood 🏡 — and here's the entire friend group, in the exact order they were introduced, no cutting the guest list:

like, that's the whole group chat and every single one of them is invited 🫶 go say hi.

and that's the page, bestie!! 🧚 this lil beauty lives in ./kernel/cgroup and it's dated October 2026 — mwah, slay, periodt 💅💖🍓
