get_option_value() is used to get the value of $1 configured in /etc/kdump.conf. But when we use "get_option_value ssh", it can get the value of "sshkey" instead of "ssh". Fix the regexp pattern to get an exact match. Signed-off-by: WANG Chao <chaowang@redhat.com> Acked-by: Baoquan He <bhe@redhat.com>
