Author: cognet Date: Thu May 24 21:38:18 2018 New Revision: 334189 URL: https://svnweb.freebsd.org/changeset/base/334189 Log: Import CK as of commit 0f017230ccc86929f56bf44ef2dca93d7df8076b. This brings us the renaming of fields in ck_queue, so that our own LIST/SLIST/TAILQ/etc won't accidentally work with them.
