Hello,
I measuring the cfs scheduling delay, and found that
when a cfs_rq contains multiple tasks, it does not guarantee
every se of this cfs_rq can get a changce to run within
one sched_latency period. Assume that there are three se
A, B, and C in cfs_rq, and the default sched_latency=24ms.
In
;env->imbalance"， and after move，
"src_rq" and "dst_rq" is balanced.
Am I right?

The jugement whether imbalance reached changed from twice to one-half.

(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.
