Subject: lib/cpuset: Skip optarg duplication
X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=e41758c6194fcb92cc6e9d136984bc6c4ceb59b7;p=thirdparty%2Futil-linux.git

lib/cpuset: Skip optarg duplication

Fix potential memory leaks and clarify that content of these strings
is never modified. Won't happen since this is test code, but adjust it
for completeness.
