Well I wouldn't say it's *required* just makes this particular piece
of code neater, since we memset-zero the node's inode_item _anyways_.
I like the constructor idea though, do you suggest I should invest in
that idea?

You're right, taking out that atomic_set was really stupid. I'll
resent the patch with a proper explanation in the commit message and
put the atomic_set back.
Unless you feel that the change is rather pointless, I'll gladly back
off :-).
