From 97d88ac83540f9ba9536326c30db4815c5b9169b Mon Sep 17 00:00:00 2001 From: Paolo 'Blaisorblade' Giarrusso Date: Mon, 30 Oct 2006 22:07:03 -0800 Subject: [PATCH] [PATCH] uml ubd driver: allow using up to 16 UBD devices With 256 minors and 16 minors used per each UBD device, we can allow the use of up to 16 UBD devices per UML. Also chnage parse_unit and leave to the caller (which already do it) the check for excess numbers, since this is just supposed to do raw parsing.
