Hi  Waiman,  Peterz,

We test new patch basing on user requested affinity patchset(the latest tip tree).

You use 7 patch from ACK code . You check following  link change.
https://android-review.googlesource.com/c/kernel/common/+/2266724
https://android-review.googlesource.com/c/kernel/common/+/2266744
https://android-review.googlesource.com/c/kernel/common/+/2266745
https://android-review.googlesource.com/c/kernel/common/+/2266804
https://android-review.googlesource.com/c/kernel/common/+/2266784
https://android-review.googlesource.com/c/kernel/common/+/2267468
https://android-review.googlesource.com/c/kernel/common/+/2267664

You can confirm this with google team and check
https://partnerissuetracker.corp.google.com/u/0/issues/256578302 .

Hi  Peterz ,

Could you help merge
https://lore.kernel.org/all/20221125023943.1118603-1-longman@redhat.com/

We want to provide better product for user.
Thanks

David.

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.

Cheers,
Longman
