Subject: [PATCH 13/15] cifs: on multiuser mount, set ownership to current_fsuid/current_fsgid
Date: Mon, 20 Sep 2010 16:01:42 -0700 [thread overview]
Message-ID: <1285023704-2159-14-git-send-email-jlayton@redhat.com> (raw)
In-Reply-To: <1285023704-2159-1-git-send-email-jlayton-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>
...when unix extensions aren't enabled. This makes everything on
the mount appear to be owned by the current user.
