A possible compromise (although I don't think vn_open() can handle it)
is to skip the naming layer altogether and just have nnpfs and arlad
pass around file handles (of the getfh()/VFS_FHTOVP() variety). Then
you don't have to worry about naming since you're just accessing the
cache files by inode, and the kernel takes care of managing the vnodes
for you.
