Note that these arguments on DISCONTIG are flame bait for many SGIers. We usually see this as an attack on DISCONTIG/VMEMMAP which is the existing best performing implementation for page_to_pfn and vice versa. Please lets stop the polarization. We want one consistent scheme to manage memory everywhere. I do not care what its called as long as it covers all the bases and is not a glaring performance regresssion (like SPARSEMEM so far).
The main conceptual difference (in my mind) was not having one bastardized data structure (pg_data_t) that meant different things in different situations (is it a node, or a section of discontig mem?). Also we didn't support discontig mem within a node (at least with the old discontigmem), which was partly the result of that hybridization.
Beyond that, it's just naming really. M. - 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/
