[PATCH 4/4] inotify/dnotify: should_send_event shouldn't match on FS_EVENT_ON_CHILD

[Eric Paris <eparis@redhat.com>]

inotify and dnotify will both indicate that they want any event which came
from a child inode.  The fix is to mask off FS_EVENT_ON_CHILD when deciding
if inotify or dnotify is interested in a given event.
