Author: mjg Date: Fri Oct 20 03:38:58 2017 New Revision: 324788 URL: https://svnweb.freebsd.org/changeset/base/324788 Log: amd64: __exclusive_cache_line pv_chunks_mutex and pv_list_locks Note that pv_list_locks is an array and currently it fits 2 locks per line. Resizing it and/or putting more locks in different lines requires several tests.
