Author: jkim Date: Mon Aug 2 18:12:30 2010 New Revision: 210780 URL: http://svn.freebsd.org/changeset/base/210780 Log: Rearrange struct pcb. r177532 (CVS r1.64 of pcb.h) moved pcb_flags to make better use of cache lines by placing it before pcb_save (now pcb_user_save), which is moved to the end of pcb since r210777.
