Re: [PATCH] cgroup/cpuset: make DL attach bandwidth reservation root-domain aware

Hi,
For another case Waiman raised while reviewing the "record DL BW
alloc CPU for attach rollback" patch, I did some validation and
summarized the test results here:
https://lore.kernel.org/all/d683b3c8-f746-47cd-a306-314a8f3eecea@xxxxxxxxxx/
In short, the data there shows that the same-root-domain case can
indeed leave persistent extra DL bandwidth accounting before the fix,
while the follow-up patch removes that growth and still preserves the
expected cross-root-domain bandwidth transfer behavior.
Thanks,
Guopeng
