Author: kib Date: Fri May 18 10:23:47 2012 New Revision: 235603 URL: http://svn.freebsd.org/changeset/base/235603 Log: Do not double-reference the found vm object in cdev_pager_lookup(). vm_pager_object_lookup() already referenced the object. Note that there is no in-tree consumers of cdev_pager_lookup(). The only known user of the function is i915 gem driver, which is not yet imported. This should make the KPI change minor.
