Author: marius Date: Sun Mar 22 21:31:02 2009 New Revision: 190289 URL: http://svn.freebsd.org/changeset/base/190289 Log: MFC: 190107 (partial) - There's no need to wrap kdb_active and kdb_trap() in #ifdef KDB as they're always available. - Remove unused variable. [1] - Add a missing const. - Sort includes.
