[PATCH v3 2/2] sched_ext: rename tg->scx.idle to tg->scx.sched_idle

[Tao Cui]

From: Tao Cui <cuitao@xxxxxxxxxx>

A bare "idle" reads as CPU idle state in sched_ext (ops.update_idle(),
idle cpumasks, scx_bpf_pick_idle_cpu()). cpu.idle is the cgroup analog
of the SCHED_IDLE policy, so name the task_group field sched_idle to
match scx_cgroup_init_args.sched_idle.

Pure rename, no behavior change.
