π move_remote_task_to_local_dsq β Kernel API Manual β¨
okay so bestie, welcome to the move_remote...to_local_dsq(9) page π this is the kernel API manual and yes we're gonna read the whole thing together, no skipping, periodt.
πΈ NAME πΈ
move_remote_task_to_local_dsq β moves a task from a foreign rq to a local DSQ π¦
β¨ SYNOPSIS β¨
void move_remote_task_to_local_dsq (struct scx_sched *sch , struct
task_struct *p , u64 enq_flags , struct rq *src_rq , struct rq *dst_rq
);
like, that's the whole signature, copy it exactly, don't @ me π
π«Ά ARGUMENTS π«Ά

π DESCRIPTION π
So what it does: it moves p, which is currently chilling on src_rq, over to dst_rq's local DSQ. That's it. That's the whole vibe π¦β¨
