Author: grehan Date: Fri Oct 26 22:32:26 2012 New Revision: 242163 URL: http://svn.freebsd.org/changeset/base/242163 Log: Set the valid field of the newly allocated field as all other vm page allocators do. This fixes a panic when a virtio block device is mounted as root, with the host system dying in vm_page_dirty with invalid bits.
