You might try going into debugfs, finding the inode, and seeing if you can tell it it's not deleted anymore.

It's very, very risky, and you risk corrupting your entire filesystem doing that. I wouldn't do it personally unless I had good backups.
Let me know if you try it and it works - that would make a good howto somewhere.

Here's the situation - I have video file, currently open
in Mplayer, which I accidentally deleted from its directory.
So, the storage and inode still exist as long as I don't
close the Mplayer.
Does anyone know of a way, using available commands or via
system calls in a program, to reestablish a link from a
directory to the inode?
