Author: alc Date: Thu Oct 27 15:51:39 2016 New Revision: 308002 URL: https://svnweb.freebsd.org/changeset/base/308002 Log: It's already the case that we repurpose the variable "pq" over the course of vm_pageout_scan() to refer to both the inactive and active queues. Use it for the laundry queue as well.
