We (ocfs2) are looking to add a new attribute to denote files that

That's an interesting set of semantics, and it might make sense to
conflate that with a local disk "don't move or defrag" the file
option. I'm not crazy with the name "static", since it could mean a
number of other things in other contexts, but I admit I can't think of
a better name.
For what it's worth, this sort of seems to be what one would expect if a
file is *both* "fixed" and "immutable".
