While testing Prateek's throttle series, I noticed a panic issue when
coresched is enabled and bisected to this patch.
I fed the panic log and this patch to an agent and its analysis looks
correct to me(cpu56 and cpu57 are siblings in a VM):
cpu57 (holds core-wide lock)
pick_next_task() [core scheduling]
for_each_cpu_wrap(i, smt_mask, 57):
i=57: pick_task(rq_57)
pick_task_fair(rq_57)
-> picks task A
rq_57->core_pick = task A
// task_rq(A) == rq_57
i=56: pick_task(rq_56)
pick_task_fair(rq_56)
cfs_rq->nr_queued == 0
goto idle
sched_balance_newidle(rq_56)
raw_spin_rq_unlock(rq_56)
// core-wide lock released
newidle_balance() pulls
task A: rq_57 -> rq_56
// task_rq(A) == rq_56 now
raw_spin_rq_lock(rq_56)
// core-wide lock re-acquired
return > 0
goto again
pick_task_fair(rq_56)
-> picks task A
rq_56->core_pick = task A
// first loop done
// rq_57->core_pick is still task A (set before lock release)
// but task_rq(A) == rq_56 now
next = rq_57->core_pick // = task A
put_prev_set_next_task(rq_57, prev, task A)
__set_next_task_fair(rq_57, task A)
hrtick_start_fair(rq_57, task A)
WARN_ON_ONCE(task_rq(task A) != rq_57)
// task_rq(A) == rq_56
I applied below diff and the problem is gone:
diff --git a/kernel/sched/fair.c b/kernel/sched/fair.c

Full dmesg of the panic is attached for your reference.
