Alternative is to keep file names around. Keeping dentries or inodes is 
just a shortcut. With a suitable file system structure (not too big
directories, multiple directories) even keeping file names and opening
on demand should be no problem, because the directory cache in the kernel 
will cache the lookup for you.
