Subject: [1/1] Use pid in inotify events.
Hi.
Attached patch puts pid into unused cookie field in inotify events.
Cookie from move command were not changed.
Having pid of the event origin is very useful for the notification
daemons which have to differentiate 'local' and 'remote' users, i.e.
those which have different policies. One of the examples is libionotify
(an IO notiication library) and POHMELFS server.
Also fixed several whitespace issues.

2. POHMELFS
