Do you still have the vmlinux file you built?  Would you mind sending it
to me along with your .config?  It's actualy quite normal to get a
negative dentry down in that code and it shouldn't cause a problem.  I
don't see any likely candidates about would like to try to figure out
exactly where in fsnotify it hit that NULL....
