In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
Say Y here to enable legacy in kernel inotify support. Inotify is a
file change notification system. It is a replacement for dnotify.
This option only provides the legacy inotify in kernel API. There
are no in tree kernel users of this interface since it is deprecated.
You only need this if you are loading an out of tree kernel module
that uses inotify.

For more information, see Documentation/filesystems/inotify.txt

If unsure, say N.
