Subject: [GIT PULL] cgroup fixes for v4.14-rc3

Hello, Linus.

The recent migration code updates assumed that migrations always
execute from the top to the bottom once and didn't clean up internal
states after each migration round; however, cgroup_transfer_tasks()
repeats the inner steps multiple times and the garbage internal states
from the previous iteration led to OOPS.  Waiman fixed the bug by
reinitializing the relevant states at the end of each migration round.

Thanks.
