  • 945526846   dnotify: ignore FS_EVENT_ON_CHILD ... Browse Code »

    Mask off FS_EVENT_ON_CHILD in dnotify_handle_event(). Otherwise, when there
    is more than one watch on a directory and dnotify_should_send_event()
    succeeds, events with FS_EVENT_ON_CHILD set will trigger all watches and cause
    spurious events.

    This case was overlooked in commit e42e2773.

  • 520dc2a52   fsnotify: use def_bool in kconfig instead of letting the user choose ... Browse Code »

    fsnotify doens't give the user anything. If someone chooses inotify or
    dnotify it should build fsnotify, if they don't select one it shouldn't be
    built. This patch changes fsnotify to be a def_bool=n and makes everything
    else select it. Also fixes the issue people complained about on lwn where
    gdm hung because they didn't have inotify and they didn't get the inotify
    build option.....

  • 272eb0148   filesystem notification: create fs/notify to contain all fs notification ... Browse Code »

    Creating a generic filesystem notification interface, fsnotify, which will be
    used by inotify, dnotify, and eventually fanotify is really starting to
    clutter the fs directory. This patch simply moves inotify and dnotify into
    fs/notify/inotify and fs/notify/dnotify respectively to make both current fs/
    and future notification tidier.
