Suppose there are 2 CPUs racing inode hash lookup func (say ilookup5()) and unlock_new_inode(). In principle the latter can clear the I_NEW flag before prior stores into the inode were made visible. The former can in turn observe I_NEW is cleared and proceed to use the inode, while possibly reading from not-yet-published areas.
