In olden times, when people didn't know how to write, they sent a courier with a letter. Now we can write messages from parasite, so SET_PARASITE_RET may be dropped. Signed-off-by: Andrey Vagin <avagin@openvz.org> Looks good to me as well. Maybe we will refine messages to be able to identify where exactly parasite failed (say line). But it better to do in another patch. Acked-by: Cyrill Gorcunov <gorcunov@openvz.org> Signed-off-by: Pavel Emelyanov <xemul@parallels.com>
