The resource name parameter should never be changed by DLM so we declare it as const. At some point it is handled as a char pointer, a resource name can be a non printable ascii string as well. This patch change it to handle it as void pointer as it is offered by DLM API. Signed-off-by: Alexander Aring <aahringo@redhat.com> Signed-off-by: David Teigland <teigland@redhat.com>
