The new fsnotify infrastructure (starting at 90586523 ) causes an oops in spufs, where we populate a directory with files before instantiating the directory itself. The new changes seem to have introduced an assumption that a dentry's parent will be positive when instantiating. This change makes it once again possible to d_instantiate a dentry with a negative parent, and brings __fsnotify_d_instantiate() into line with inotify_d_instantiate(), which already has this NULL check.
