Subject: Fixed total space display when data size exceeds quota
X-Git-Tag: v7.0.0alpha2~645^2
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=010eef95c0c5cebd03b03645d29847638e064bd5;p=nextcloud-server.git

Fixed total space display when data size exceeds quota

The total space display in the personal page now shows the quota value
instead of used space when used space exceeds the quota (soft quota).
