Subject[PATCH 5/5] sched/fair: remove useless check in select_idle_core
Date
The function only gets called when sds->has_idle_cores is true
which can be possible only when sched_smt_present is enabled.
This change also aligns select_idle_core with select_idle_smt
that the caller do the check if necessary.
