Why is that spinlock protection there?
Isn't this a new inode that cannot possibly be reached any other way yet?
NOTE! This is a question. Maybe there is something I missed, and there
*are* other ways to reach that inode. But if that's true, isn't it
already too late to set I_CREATING?
So I'd like some clarification on this point before applying it. It's
possible that the spinlock is required, I just want to understand why.
