Author: attilio Date: Mon Jun 23 09:35:13 2014 New Revision: 267783 URL: http://svnweb.freebsd.org/changeset/base/267783 Log: Add a new pagequeue, called "disposed". This is going to be used as an high-priority inactive queue, more or less, with specific constraint. It is going to give vm_page_advise() the ability to free some pages in steady way.
