Look more carefully. It's path->dentry; aside of the fact that dentry pointer is fetched at offset 8 from one of the arguments (fits path->dentry, too low for mnt->mnt_root), do_add_mount() itself has just done S_ISLNK on the very same thing, so it'd die before getting to graft_tree().
No, it's either path_lookup() somehow returning a negative dentry in do_mount() (which shouldn't be possible, unless it's some crap around return_reval in __link_path_walk()) or it's follow_down() giving us a negative dentry. Which almost certainly would've exploded prior to that...
