I don't have a strong opinion on the feature, but the open question
we should get some decision on is whether it's really well applicable to
a good enough set of apps / workloads, if it'll even be useful in the
future and/or for other vendors, and if the merit outweighs extra
8 bytes + 1 flag per io_kiocb and the overhead of 1-2 static key'able
checks in hot paths.
