There has been quite a bit of work in the slub allocator to mitigate inode and dentry memory usage. Late 2007, early last year from memory. Badly designed code can eat memory this way as per the link from Brad - updatedb is the typical flogging horse. I'd be inclined to run slabtop sorted on cache size to see what is actually being used, and by whom - no prizes for picking the top 2 likely candidates.
