[Question] load balance move tasks not suitable ?

[weiqi (C)]

Hi Peter,

After  Commits 5d6523ebd(sched: Fix load-balance wreckage)，
The jugement whether imbalance reached changed from twice to one-half.
from

(1) if((load * 2)> rem_load_move)
        goto next;

to

(2) if((load / 2)> env-> load_move)
        goto next;

I'm confused about this change.

"load*2" may be more appropriate, because if a task whose load more than 
env->imbalance is moved from high load cpu to low load cpu,

will make more imbalance.

Regards,
