Hrm. Looking at the code, I noticed that the opposite is true:

destroy_filldir_cache();
destroy_inode_cache();
destroy_dentry_cache();
unregister_filesystem(&unionfs_fs_type);

The last one in particular...

If I make the *args = data line const, then gcc (4.1) yells about modifying
a const variable 3 lines down..

args->err = vfs_mknod(m->parent, m->dentry, m->mode, m->dev);

Sure, I could cast, but that seems like adding cruft for no good reason.
