* As part of this change, I found an error in the union filesystem. In
* union_copyup() (called when we need to copy a file from the lower layer to
* the upper), we would lock the file we were going to copy, but only unlock
* it if we successfully opened it. This change was not in the patches I sent
* to tech-kern.
