BTW, do we have a use case for double_lock_guard/double_lock_scope? I
can envision a nested lock_scope inside a lock_scope, but taking 2
auto locks of the same type at init time and then unlock them at exit
just doesn't make sense to me.
AFAIU taking both runqueue locks for source and destination runqueues
on migration is one use-case for double_lock_guard/scope.
I see. Thanks for the clarification. I forgot about that special case.
Cheers,
