devpts: add fsnotify create event
Currently, devpts doesn't generate an fsnotify event upon pts creation because the regular vfs paths aren't involved. Deallocation, on the other hand, correctly generates a nameremove event thanks to the d_delete() invocation in devpts_pty_kill(). This patch adds the missing fsnotify_create() trigger in devpts_pty_new(). Signed-off-by: Florin Malita <fmalita@gmail.com> Acked-by: H.
