you should use this name "just in case", unless you have some really good

ramfs

Why would ramfs want its pages in this wired list? (I'm not so
familiar with it but I can't think of a reason).

Because ramfs pages cannot be paged out, which makes them locked
into memory the same way mlocked pages are.

I don't understand why they need to be on any list though,
that isn't an internal ramfs specific structure (ie. not
the just-in-case wired list).
