The reason is that it used only internally in the ngx_http_upstream_cache()
function, which is static too.  In fact, in my original version of patch the
whole code was in ngx_http_upstream_cache() but Maxim insisted on moving it
into a separate function just because the ngx_http_upstream_cache() is already
bloated.
