    fsnotify: generalize handling of extra event flags · 007d1e83
    Amir Goldstein authored
    FS_EVENT_ON_CHILD gets a special treatment in fsnotify() because it is
    not a flag specifying an event type, but rather an extra flags that may
    be reported along with another event and control the handling of the
    event by the backend.
    
    FS_ISDIR is also an "extra flag" and not an "event type" and therefore
    desrves the same treatment. With inotify/dnotify backends it was never
    possible to set FS_ISDIR in mark masks, so it did not matter.
    With fanotify backend, mark adding code jumps through hoops to avoid
    setting the FS_ISDIR in the commulative object mask.
    
    Separate the constant ALL_FSNOTIFY_EVENTS to ALL_FSNOTIFY_FLAGS and
    ALL_FSNOTIFY_EVENTS, so the latter can be used to test for specific
    event types.
