-config DNOTIFY
-	bool "Dnotify support"
-	default y
-	help
-	  Dnotify is a directory-based per-fd file change notification system
-	  that uses signals to communicate events to user-space.  There exist
-	  superior alternatives, but some applications may still rely on
-	  dnotify.
-
-	  If unsure, say Y.
-
-config INOTIFY
-	bool "Inotify file change notification support"
-	default y
-	---help---
-	  Say Y here to enable inotify support.  Inotify is a file change
-	  notification system and a replacement for dnotify.  Inotify fixes
-	  numerous shortcomings in dnotify and introduces several new features
-	  including multiple file events, one-shot support, and unmount
-	  notification.
-
-	  For more information, see <file:Documentation/filesystems/inotify.txt>
-
-	  If unsure, say Y.
-
-config INOTIFY_USER
-	bool "Inotify support for userspace"
-	depends on INOTIFY
-	default y
-	---help---
-	  Say Y here to enable inotify support for userspace, including the
-	  associated system calls.  Inotify allows monitoring of both files and
-	  directories via a single open fd.  Events are read from the file
-	  descriptor, which is also select()- and poll()-able.
-
-	  For more information, see <file:Documentation/filesystems/inotify.txt>
-
-	  If unsure, say Y.
