Just reverting #3[0] on 2.6.16 doesn't fix it either. Peter, back on 2.6.14.2 for now. 0. one hunk didn't unapply cleanly, and the change was not obvious. I opted for making the beginning of xfs_probe_cluster() look like: | /* First sum forwards in this page */ | do { | if (!buffer_uptodate(bh) || (mapped != buffer_mapped(bh))) | return total; | total += bh->b_size; | } while ((bh = bh->b_this_page) != head); - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
