I'd really like to get this done at the same time as the io_uring change. Are you open to doing the READ_ONCE() based JOBCTL_TASK_WORK addition for 5.9?

Yes, the patch looks fine to me. In fact I was going to add this optimization from the very beginning, but then decided to make that patch as simple as possible.

And in any case I personally like this change much more than 1/2 + 2/2 which I honestly don't understand ;)
