[PATCH 1/1] fallocate: create FAN_MODIFY and IN_MODIFY events

[Heinrich Schuchardt]

The fanotify and the inotify API can used to monitor changes of the file
system.

System call fallocate modifies files. Hence it should trigger the corresponding
fanotify (FAN_MODIFY) and inotify (IN_MODIFY) events.

This patch adds the missing call to fsnotify_modify.
