Author: markj Date: Wed Jul 20 00:09:22 2016 New Revision: 303052 URL: https://svnweb.freebsd.org/changeset/base/303052 Log: Make vm_pageout_wakeup_thresh a u_int rather than an int. It's a threshold for v_free_count, which is of type u_int. This also lets us get rid of a cast in vm_paging_needed().
