Question about scheduler load balancing

From: Gaurav Poothia

Hello
Presumably the scheduler load balancing logic is less reluctant to
load balance tasks at higher level scheduling domains (e.g. cross
NUMA) than lower level SD
Is that true?

If yes, which knobs (or hardcodes) drive the load_balance() function
to vary how aggressively it balances when it is invoked for different
SD levels?

Thanks in advance!
Gaurav
