Re: reiser4 performance

Forgive me for moving to private, but I've posted this on the list before 
without comment.

The 2.6.12.x patches and 2.6.12.x applied from -mm have incorrect behavior 
when modifying the root directory. If you add or remove files in the root, 
the filesystem check fails. You can try this on a ram disk or loop file 
system. I'd be interested to see if you'd try it and let me know if you get a 
failed filesystem check. I am able to repair without data loss.
