This is pretty inefficient for ext2fs. We walk the entire block group containing the inode, searching through every directory for an entry referencing this inode. It might be a good idea to cache this information somehow. I'm not sure how often we'll be searching for it. Obviously there are multiple caching layers missing in the file system.
