  I'm happy the patches finally appply fine for you :).

  No, the quotactl won't fail because OCFS2 kernel module overloads
function implementing the Q_QUOTAON handling and so filename is actually
ignored and it provides corresponding system inode instead.

  It is strange that they don't work for you. Are you using the version of
quota-tools I sent you (like week ago after I sent the first set of
patches)? Because the changed version of quota-tools works here for me just
fine... I'm attaching it to this mail again just in case it got lost somewhere.

  Well, having your own tool for turning quotas on is possible as well, but
I think it would be better if you used provided quota-tools.
