On OPEN is good. If "p" already exists (and has content), then file size 
will be more than 0. In your example "p" did not exist, which is why the 
file size was 0.

For example, when I run:

$ vi /etc/hosts

I see:

OPEN   uid:1000 pid:1988 mode:438 flags:0 file_uid:0 file_gid:0 
file_device:774 file_size:551 file:/etc/hosts
CLOSE  uid:1000 pid:1988 file:/etc/hosts

Since the file already existed (with content), I see a file size larger than 0.
