H A D | deadline.c | 772b6539 Wed Mar 02 12:34:30 CST 2022 Dietmar Eggemann <dietmar.eggemann@arm.com> sched/deadline: Merge dl_task_can_attach() and dl_cpu_busy()
Both functions are doing almost the same, that is checking if admission control is still respected.
With exclusive cpusets, dl_task_can_attach() checks if the destination cpuset (i.e. its root domain) has enough CPU capacity to accommodate the task. dl_cpu_busy() checks if there is enough CPU capacity in the cpuset in case the CPU is hot-plugged out.
dl_task_can_attach() is used to check if a task can be admitted while dl_cpu_busy() is used to check if a CPU can be hotplugged out.
Make dl_cpu_busy() able to deal with a task and use it instead of dl_task_can_attach() in task_can_attach().
