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?
Beside being tunneled visioned towards LTS only, nope.
They apply cleanly on 6.4.y and preparing the patches now. I'm not sure I can run any tests on 6.4.y though except maybe boot test on qemu.
Waiting for compile tests to finish and will post shortly.
Thanks!
