Author: kib Date: Mon Feb 6 10:35:21 2012 New Revision: 231072 URL: http://svn.freebsd.org/changeset/base/231072 Log: MFC r230785: A debugger which requested PT_FOLLOW_FORK should get the notification about new child not only when doing PT_TO_SCX, but also for PT_CONTINUE. If TDB_FORK flag is set, always issue a stop, the same as is done for TDB_EXEC.
