Negative caching is done when deleting files, but I cannot see any
negative caching when lookup returns ENOENT. Is there a reason why this
feature is not implemented? It speeds up things like compiling and make
quite a bit.

If I want to implement this feature in my filesystem, does anyone have any
bright ideas on how to do it, like d_allocing my own dentry, leaving the
inode == NULL and do a d_add?
