Is that correct? It's bug if it does that. The code related to NOTIFY_DELETE in fuse_reverse_inval_entry() seems historic. It's supposed to be careful about mountpoints and referenced dentries, but d_invalidate() should have already gotten all that out of the way and left an unhashed dentry without any submounts or children. The checks just seem redundant, but not harmful. If you are managing to trigger the ENOTEMPTY case, then something strange is going on, and we need to investigate. Thanks, Miklos
