If an application (say, a layered FS) wanted to store additional
opaque data, perhaps it allocates a new file, and stores a pointer
(via inode number) to it.  Userland applications could do this as

Really, vnextops is orthogonal to the opaque data storage.  It's being
used in the upper layer that Bill is working on (a data migration layer)
for other things.  Hence the separated "generic" vs. "fs specific" namespace.
