That info is already part of the second line isn't it ? ie [ 0.473417] HugeTLB registered 16 GB page size, pre-allocated 0 pages pre-allocated 0 pages indicate we didn't allocate anything. So why do we need to add more details fo kernel output ? -aneesh _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
