+ * handled by fscrypt_prepare_rename() and fscrypt_prepare_link().)
+ *
+ * This is necessary because creating a filename requires the directory's

+ * the final filesystem operation doesn't guarantee that the key was available
+ * during the preceding dentry lookup.  And the key must have already been
