Test generic/422 hardcodes in the output file how much space files it creates are supposed to take up on disk. This doesn't work when additional space is allocated for extended attributes for ACLs or SELinux labels. Instead, record the actual space used in generic/422.full, and only check if the writeback changes the space used.
