I just wanted to show that this is not a security problem.
Since there are others probably even more important.
But I really do not want to start to discuss this, since I already see
that result will be effectively zero, so returning to the original
problem with putting pid into events: if inotify_init() caller has 0
(e)uid or if IO origin has the same (e)uid, are you ok to put pid into
the event?
