[PATCH 1/2] fsnotify: make fsnotify_create() agnostic to file/dir

[Amir Goldstein <amir73il@gmail.com>]

Like fsnotify_delete(), let fsnotify_create() handle creation of both
dir and non-dir objects, if d_inode is available at creation time.

Unlike fsnotify_rmdir(), we do not call fsnotify_create() from
fsnotify_mkdir(), because of the case where d_inode is instantiated
lazily (e.g. kernfs).
