scx_rehome_task(9)

✨ NAME ✨

okay bestie, meet scx_rehome_task(9) from the Kernel API Manual — the function whose whole job is Move a task to a sched it has been initialized for. iconic, honestly. 💖

🌸 SYNOPSIS 🌸

void scx_rehome_task (struct scx_sched *to , struct task_struct *p );

🎀 ARGUMENTS 🎀

• to — the sched taking over p; p's init on it already complete.
• p — the task to re-home.

💖 DESCRIPTION 💖

okay so check it: scx_rehome_task exits p from its current sched and switches it over to to. It overrides the state to SCX_TASK_READY to account for the already completed init — yes, the init is already done, that's the whole point. 💅

and the edge case? a task on a non-ext class — possible under an SCX_OPS_SWITCH_PARTIAL root — stays READY, and switching_to_scx enables it if it switches over. 🦋
