Author: jhb Date: Sat Aug 29 02:17:40 2009 New Revision: 196637 URL: http://svn.freebsd.org/changeset/base/196637 Log: Mark the fake pages constructed by the OBJT_SG pager valid. This was accidentally lost at one point during the PAT development. Without this fix vm_pager_get_pages() was zeroing each of the pages.
