Well, the patch only has any impact when the order you are reclaiming is less than PAGE_ALLOC_COSTLY_ORDER so I would not have considered it of major impact to other projects interested in high order allocations. However, in isolation I have no problem with this patch and I can see how it makes sense for the problem scenario described. I rebased just this patch to 2.6.24-rc7 and found no problems but I have not had the chance to review the whole set. > Reviewed-by: Christoph Lameter <[EMAIL PROTECTED]> > Acked-by: Mel Gorman <[EMAIL PROTECTED]> -- Mel Gorman Part-time Phd Student Linux Technology Center University of Limerick IBM Dublin Software Lab -- 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/
