Can we determine which /proc/sys entries these are?
Colin Ian King narrowed it down to
/proc/sys/kernel/sched_domain/cpu0/domain0/flags
and commit 5b9f8ff7b320a34af3dbcf04edb40d9b04f22f4a.
He has a proposed patch, too, that he'll be sending to the list soon.
See https://bugzilla.kernel.org/show_bug.cgi?id=209919#c9
Thanks for the quick debugging, Colin!
