Description Petr Pisar 2016-02-10 09:52:20 UTC

If passwd database is remote, enumerating all users is expensive. Then repquota tool cannot list quota entries for filesystems that do not export list of users with quota in use. That's the case of XFS.

Recently, Linux gained new Q_XGETNEXTQUOTA and Q_GETNEXTQUOTA qutoactls to enumerate file system users with quota in use. Once this kernel interface appears in Fedora, we can extend user space quota tools to utilize the new feature.

It has already been implemented in upstream with commits:

    scanning all dquot structures.

This feature requires a new kernel interface that will be available probably in linux-4.6.
