Subject: LU-3754 mdt: Enable data_version control
X-Git-Tag: 2.4.92~37
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=29c75754814f391682a96c44715cfa4b1f21354c

LU-3754 mdt: Enable data_version control

When LU-1333 was landed, all HSM infrastructure was not yet landed and
it was not possible to archived a file. As a consequence, the original
patch did not compare on-disk archived data version and current file
data version.
Now, everything required is there and we should enable this
verification.
