This standalone patch has been superseded by the v4 series. The scheduler
task-tick framework has since been reworked to dispatch both the donor and
execution classes, and the RT watchdog fix has been rebased and folded into
patch 4/5.

The v4 series is available at:

https://lore.kernel.org/r/20260909092901.2989564-1-sh_def@xxxxxxx

The task-tick framework redesign was discussed in Peter Zijlstra's review:

Please consider this standalone patch superseded.

Thanks,
