We've been down this path before:
http://marc.theaimsgroup.com/?l=linux-kernel&m=114861109717260&w=2
A lot of comments on per-sb unused dentry lists were made in the threads associated with the above. other solutions were found to the problem that the above patch addressed, but I don't think any of them have made it to mainline yet. You might want to have a bit of a read of these threads first...
