Exactly, no other recourse here than to just revert it. Unfortunately
my io_uring-7.2 branch is from pre merging of the epoll changes, as those
went in separately. Hence I can either prep a revert for you separately,
or you can just revert cfa1539b24af yourself since you have the context
as well. Let me know what you prefer!
