Author: asomers Date: Tue Aug 1 16:00:21 2017 New Revision: 321878 URL: https://svnweb.freebsd.org/changeset/base/321878 Log: MFC r320737, r320914 r320737: Fix cleanup in lib/libc/gen/setdomainname_test ATF cleanup routines run in separate processes from the tests themselves, so they can't share global variables. Also, setdomainname_test needs to be is_exclusive because the test cases access a global resource.
