Anders Blomdell noted in 2010 that Fanotify lost events and provided a
test case.  Eric Paris confirmed it was a bug and posted a fix to the
list
  https://groups.google.com/forum/?fromgroups=#!topic/linux.kernel/RrJfTfyW2BE
but never applied it.  Repeated attempts over time to actually get him
to apply it have never had a reply from anyone who has raised it
So apply it anyway
