> To reproduce:

>     sudo sh -c 'echo 10 > /proc/sys/fs/inotify/max_user_watches'
> 2) Create a file:
>     touch /tmp/hello
> 3) Follow it:
>     tail -f /tmp/hello

> Result:
> tail: cannot watch `/tmp/hello': No space left on device

> Expected result:
> tail: cannot watch '/tmp/hello' because inotify reported: No space
