🦋 scx_cgroup_task_migrated(9) — Kernel API Manual 🦋

🌸 NAME 🌸

scx_cgroup_task_migrated — re-home a task that changed cgroups. literally the relocation glow-up for a task that switched cgroups 💅

---

✨ SYNOPSIS ✨

void scx_cgroup_task_migrated (struct cgroup_task_migrate_ctx *ctx );

---

🎀 ARGUMENTS 🎀

• ctx — committed migration. that's the migration that's already committed, bestie — no take-backs 💖

---

💅 DESCRIPTION 💅

Move the task to its new cgroup's sched, which scx_cgroup_task_migrating already initialized it for. Can't fail. periodt. ✨

This is safe against all phases of the destination sched's destruction. no cap. 🫶

A disable resets cgroup ownership to the parent and re-homes tasks in one scx_cgroup_lock section. If that section already ran, the destination would be the parent. Otherwise, the re-home loop is still ahead and guaranteed to visit the task, now in the destination cgroup. iconic behavior, honestly 👑
