Paul,
Thanks again for your comments. You are right, the d_count is
getting mucked up through the __emul_lookup_dentry() path. I also
discovered some problems with the way I was taking the dcache_lock.
So I will go back and try to fix those.
I saw your patch for path_lookup. The next version of fast walk
will include those changes (I had started making the changes before seeing
your patch anyway).
Hanna
