You would pass NODE_MASK_ALL if your intent was to interleave over everything you have access to, yes. Otherwise you can pass whatever you want access to and your interleaved nodemask becomes mpol_rebind_policy()'s newmask formal (the cpuset's new mems_allowed) AND'd with pol->passed_nodemask. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
