Subject: [PATCH 4/5] rt-tests: pip - Use check_privs() from the rt-utils library.

Message-ID: <1261584180-13922-5-git-send-email-jkacur@redhat.com> (raw)
In-Reply-To: <1261584180-13922-4-git-send-email-jkacur@redhat.com>

Use check_privs() from the rt-utils library to make sure that the user is
running with real-time privileges for the pip test program.
