h shouldn't be blocker for this
loop perf improvement.

Secondly it isn't enough to replace nowait decision from user side, one
case is overwrite, which is a nice usecase for nowait.
As I mentioned the hint in this patch is very loop specific for avoiding
potential write perf regression, which just works for loop's case.

It can't be applied on io-uring, otherwise perf regression can be caused on
overwrite from io-uring application.

So I don't know what is the exact common code or logic for both loop and
io-uring.


Thanks,
