Hi, Waiman

We use 140 devices to test this patch 72 hours. The issue can not be reproduced. If no this patch, the issue can be reproduced.
Could you help merge this patch to mailine?

https://lore.kernel.org/all/20221125023943.1118603-1-longman@xxxxxxxxxx/

If this patch is applied to the maintainer's tree, we can request google to help cherrypick to ACK to fix issue.

Just want to clarify if you are testing the patch using the latest tip tree or on top of an existing linux version without the persistent user requested affinity patchset.

PeterZ is the scheduler maintainer who is responsible for merging scheduler related patch. It is up to him as to when that will happen.
