Heh, yes, you can take mlock()'d into account. But the fun part is that that
field doesn't account for file vs. anonymous mlocks. Perhaps we should spell
that one out.
No, that comment isn't wrong, it says that slabs that set the flag *claim* to
be reclaimable. That doesn't mean they're 100% reclaimable all the time, just
like ramfs and the root dentry. It just means that we expect to be able to
shrink them, not that we can *always* shrink them or that their contents are
100% disposable.
You're not addressing my main point, though, which is that this removes the
ability to do apples-to-apples comparisons with vmstat across different
distributions. I agree with you that vmstat needs some work, and I'd be happy
to work with you to find some ways to improve it. But, I'd very much prefer to
see the default output be kept consistent historically.
