Without the patch, the "kmem -n" option incorrectly shows mem_map addresses containing the flag in bit 5 as part of the virtual address, and also the "kmem -p" option shows page structures at wrong position. With the patch, the "kmem -n" option displays the new "D" state flag. This looks good to me. Acked-by: Lianbo Jiang <lijiang(a)redhat.com <mailto:lijiang@redhat.com> > Thanks.
