    well, available in this commit at least:

    Direct IO support · zfsonlinux/zfs@a584ef2

    this has been a long time coming... first requested back in 2011. just thought anyone who's been waiting on this would like to know... finally...

    this should allow ZFS to work better with oVirt and not throw error when DirectIO is requested.
