Subject: Do not include object checksums in file contents listings.
X-Git-Url: https://git.vrable.net/?a=commitdiff_plain;h=ae5a596823b8ca4860f4487f5e228e93f73bb050;p=cumulus.git

Do not include object checksums in file contents listings.

Do not list object-level checksums as these will make the metadata larger,
and the file-level checksum already ensures the file contents on restore
are correct.
