It's some Smatch stuff that I was working on yesterday.  I'm probably
going to publish this in a month or two.  It's hard to say because, of
course, returning NULL is often valid.

Anyway, the warning is triggered when you pass zero to ERR_PTR().

 	fs/ocfs2/inode.c:179 ocfs2_iget()
 	warn: passing zero to 'ERR_PTR'
