This is a backport of the series that fixes the way deadline bandwidth restoration is done which is causing noticeable delay on resume path. It also converts the cpuset lock back into a mutex which some users on Android too. I lack the details but AFAIU the read/write semaphore was slower on high contention.
Compile tested against some randconfig for different archs and tested against android14-6.1 GKI kernel.
My testing is limited to resume path only; and general phone usage to make sure nothing falls apart. Would be good to have some deadline specific testing done too.
Based on v6.1.46
I can't take these for only some branches, as you know. Any reason why you didn't also do 6.4.y?
thanks,
