have a strong opinion against it. Also just to be clear we are not talking about full revert of 58056f77502f but just the returning of EOPNOTSUPP, right?
If we allow the limit to be set without returning a failure then we still have options 2 and 3 on how to deal with that. One of them is to enforce the limit.
Option 3 is a partial revert of 58056f77502f where we keep the no limit enforcement and remove the EOPNOTSUPP return on write. Let's go with option 3. In addition, let's add pr_warn_once on the read of kmem.limit_in_bytes as well.
