- Thread-topic: [PATCH v2 4/6] xen_pvdev: Do not assume Dom0 when creating a directory
From: Oleksandr Tyshchenko <oleksandr_tyshchenko@xxxxxxxx>
Instead of forcing the owner to domid 0, use XS_PRESERVE_OWNER to
inherit the owner of the directory.
Note that for other than Dom0 domain (non toolstack domain) the
"driver_domain" property should be set in domain config file for the
toolstack to create required directories in advance.
