Author: kib Date: Wed Dec 14 23:34:25 2016 New Revision: 310097 URL: https://svnweb.freebsd.org/changeset/base/310097 Log: Remove locking around accounting initialization of the default object. The object is not yet fully constructed and must not be available to other threads. This makes default_pager_alloc() almost identical to swap_pager_alloc_init().
