Before we go and fix these test cases. Do they make any sense at all?
Why should anybody even care that the limit is in page units? I do not
see anything like that mentioned in the documentation. Sure having
the limit in page size units makes a lot of sense from the
implementation POV but should userspace care? Would something break if
we change internals and allow also !page_aligned values? I have hard
time to imagine that.
