Author: avg Date: Fri Sep 3 10:40:53 2010 New Revision: 212174 URL: http://svn.freebsd.org/changeset/base/212174 Log: vm_page.c: include opt_msgbuf.h for MSGBUF_SIZE use in vm_page_startup vm_page_startup uses MSGBUF_SIZE value for adding msgbuf pages to minidump. If opt_msgbuf.h is not included and MSGBUF_SIZE is overriden in kernel config, then not all msgbuf pages will be dumped. And most importantly, struct msgbuf itself will not be included. Thus the dump would look corrupted/incomplete to tools like kgdb, dmesg, etc that try to access struct msgbuf as one of the first things they do when working on a crash dump.
