 -	  Dnotify is a directory-based per-fd file change notification system

 -	  Say Y here to enable inotify support.  Inotify is a file change

 -	  numerous shortcomings in dnotify and introduces several new features
 -	  including multiple file events, one-shot support, and unmount
 -	  notification.

 -	  Say Y here to enable inotify support for userspace, including the
